They locked my account

I reached out today to support to help me get 2fa added to my account and the locked my account in attempt to “secure” it. I now can’t access my account which had over 50,000 trophies and is 6 months old. I have never let anyone else log into this account or done anything to break ToS. Has anyone else had this experience? I’ve submitted multiple tickets which leads to an automated bot that is no help in verifying that I am the original owner. Is there anyone on here that can help me out or point me in the right direction? I feel I have exhausted all avenues.
