Cash App

I had a secondary cash app account in which I have not used in several months and back in March someone was able to log into it and immediately unlinked my email and phone number. I made the second account sometime last year for some temporary business related things and I used a free phone number from an app. After I stopped using the cash app account and the phone number, the app revoked the free phone number and eventually reassigned the phone number to a new user. That person used the number to log into that cash app account and they unlinked and replaced the email I had connected. I realized there was an issue the other day when I tried sending one of my friends a couple dollars and it said that I had reached my monthly limit of $50,000 even though I calculated it and only spent $127. So somebody stole that account and is cycling thousands of dollars under my I.D. and SSN. I can verify the account is mine with my I.D. and SSN, but the cash app support has not been very helpful. Is there a way this account can get deleted? Is there someone important I can talk to to resolve this?

Thanks
