What country are you in? Not all of them have a number you can call.
You can also try creating a case from a different account. The advisor will be able to find the account in question and assist with this.
same here im also on the same situation as you because 2 days ago my account just got banned out of the blue after me and my friend done playing on training (mostly having fun with 1v1) and we started to queue to trio well you know the whole story my account got banned literally out of nowhere. and the customer support (the TOS team) is just extremely irritating yet unprofessional how they still accused me of cheating because they confirmed from their proof and source when reality is not and still havent checked my problem carefully and now i got " It looks like your account, or the game account where you're trying to get help, broke our rules." after i want to see their proof and information about why i got banned in the first place which still doesnt broke any their tos and rules because i read carefully because this actually violation of GDPR for not giving personal data but lucky for them i dont live in eu so they just refuse
seriously look at my game stats does this look like a cheater to them and you? because i started playing apex again in season 5 (actually season 0 but rarely played until season 5) and keep playing until this happen
the level of unprofessionalism because its their right to do so without checking carefully when someone request it and i get it but i still believe this is still a mistake and a false positive since it quite possible for something get flagged by eac which doesnt involved anything (but suspected RGB software caused the flag which also doesnt to do with apex beside controlling the desktop lighting) and my current situation is pretty much extract same thing happen to ninja last year
