my ex (F18) and her friend will not stop contacting me (M20) after we have broken up. i have blocked their numbers, but they still find a way; is there anything i can do?

hi. this is really long, but i want to provide as many details as possible to the entire story. there is a tldr at the end for the barebones, but this is essentially my entire story here.
so we were together for around 4ish months. met through a mutual friend and clicked pretty quickly, so we began dating pretty much instantly. about a month after we began dating, she went away to school — this didn’t come out of nowhere; we both went into the relationship knowing this would happen and being okay with it, just to see where we went. the first few weeks of long distance were difficult, but shortly after we fell into a real nice groove of facetiming every night while doing homework and open communication and just really really good overall.
the problems started around the time she was returning home for a family reason. she got home on a friday, ignored me all day saturday and then went out to a bar and then a party with her friends. i should also mention here that we were “best friends†on snapchat for essentially our entire relationship leading up to this point, but a few days beforehand we no longer were. i asked her about it, and she mentioned it was this guy who was just a good friend. i didn’t want to start anything, but needless to say i was slightly suspicious already. i didn’t care she went out, i get it and she hadn’t seen her friends in just as long as she hadn’t seen me. ignoring me was less cool though. i should also mention right here that despite her essentially ignoring me all day, i told her that if any of her plans for where to stay (her best friends dorm room) fell through, to let me know bc i could pick them up or whatever. the next day the location on her phone was turned off when i woke up (we both always shared our location with each other). and yes, i did feel the need to check given that this dude was apparently now her best friend on snap. she offered up that she turned off her location for everyone so her mom didn’t think that she wasn’t at her friends house or something to that effect. i was iffy but relatively okay with this.
we hung out pretty much everyday the entire next week, and it was honestly really great. everything felt normal and good and like nothing had ever happened and like we were just really really good together. this was the pinnacle of our relationship, for sure, and the next few weeks were really great as well.
then we began kinda planning out when she was coming home next, which was thanksgiving. we talked about me picking up from airport, or whatever. she began saying stuff about how she needed to talk to me then and stuff. so i was pushed a little bit because i wanted to know. she eventually caved and talked. that night, the guy that was a “friend†was at the bar and then her plans on where to stay fell through. rather than calling me, this guy offered that she and her friends could stay at his place; she accepted and slept in his bed. she insisted that nothing happened, but it plus the lying about it was enough for me. i pretty much broke up with her. after a few days of her apologizing and insisting nothing happened, i said like look let’s just talk in person when you come home. she agreed.
then she came home and i was available every single day to hang out and talk, and she had plans every single day and couldn’t. so i said fine, we won’t ever figure this out and it’s just officially over and she again apologizing and begged us to meet over christmas break. i said if i want to meet with you and talk, then i will. otherwise, you need to leave me alone.
it was around this time i tried to move on. had a one nighter, felt like **** about it, cried a lot because i was lonely and no one was her. i called her the day before she was set to come home and said we could talk. we did, and i expressed that i was willing to move on and move forward because i loved her. she said this made her realize that she needed to grow up and she was ready for that. we made up. it wasn’t the same, but i hoped it would be eventually.
new year’s eve she went out again even though i wasn’t thrilled about it and i told her that. she said that she wanted this to be her chance to prove to me that she had grown up. i was heading to a separate party, because i wasn’t invited out with her. she essentially ignored me all night again, and posted pictures of her all over a few guys on her snap story. i got wasted to the point of throwing up multiple times and crying on a couple friends immediately after the vomiting.
she expressed to me the next day that nothing happened. she explained the pictures as nothing. told me she wanted me to come over and meet her parents so she could show me she was all in (had not yet met parents...also was in no shape to meet parents, as my head felt like i had a constant stream of hammer strikes to the temple). i told her no. that i was done with everything.
around this time she got vengeful. she sent me pics/vids of her doing drugs or buying a pregnancy test, because she ****ed her ex-boyfriend. i followed by blocking her on snap and all social media. she called me on my birthday, right before she went back to school following winter break, and kept on telling me how excited she was to **** her ex that night and hang with friends that “your controlling ass never let me hang with†which was bull****. the next day, after i blocked her number, she messaged me on social media that i guess i forgot to block her on telling me she was sorry for doing that on my birthday, and she wishes me well and wishes no hard feelings. i told her there are hard feelings and to leave me the **** alone.
i have her and her friend blocked on anything that they could contact me on, except for her friend’s phone number because i did not even have it saved.
which leads to this last weekend, about a month later with essentially no interaction, when i was on spring break vacation with some friends. we went to a club one night and as soon as we walk in, i get a call from her friend, and i know it because it’s the same number as my ex’s until the last 2 digits. i decline the call, and she calls again and i answer and tell her to **** off and stop calling me; i could not even hear her because i was in a loud club. after that call, i block her number. she calls again from “no caller i’dâ€; supposedly, if you use *67 and then type in the number, it will not recognize it’s blocked and allow you through. i declined the call again. after the night ends at the club, we head back to our hotel. i won’t lie — there may have been a girl at the club that we made out, no big deal, at least it shouldn’t have been.
the minute i walk back into the hotel room and lay down in bed, still drunk as ****, i get a no caller id call. i answer and it’s my ex. asking me what happened. i told her her friend kept calling me and they both needed to **** off and leave me alone. she said she was calling me because i called her first and she didn’t know who it was; i checked my call log, because i was drunk but i didn’t even have her number saved, so it’s literally impossible i could have called it. she called me first. she wouldn’t divert from that bull**** explanation, even when i called her on it. i told her they both needed to leave me the **** alone. she had the audacity to ask how i’m doing, whether i’m okay, because i sounded not good. i wasn’t good; i wasn’t in the mental state to be having this conversation, because it’s literally just now where i’m actually feeling okay. this was one of the first weekends i felt okay and like i maybe deserve to have a love better than hers. and it was ruined and i feel like i’m back to square one.
i felt bad about kissing someone else at the club, even though i shouldn’t have, but i heard her voice for the first time in a long time and i felt like she was my only home and comfort. i felt like **** all around. i still do, and i still feel like i don’t when i’ll ever get over her and how i was hurt. most of all, how the **** do i get her and her friend to stop contacting me when i’ve blocked them on everything? i have no idea where to go next.
tldr: girlfriend probably cheated on me. broke up. blocked her. her and her friend are still contacting me and ruining my attempted progress on getting over her, even after blocking them on everything.
