Cash App complaint: Money transaction

Someone sent me money to my account on cash app. When I signed in I needed to update my bank account when I did, that changed the name on my cash app account and started a new account. I was then not able to access the old account that the money was sent to. I emailed and they were not able to see any of the transactions at first and had no records, I sent them screen shots from the sender and the notification I received on my phone. They then could see the accounts and were unable to return payment. I also do no have access to my old account unless I can provide the full credit card number of an old credit card that I no longer have. After seven of the same generic emails being sent not resolving the problem I’m very frustrated. I emailed to see if there is any other way to access this account with out having to provide the full account number, also on their website it says do not give out full account numbers as that is a scam. The first issue is not receiving payment or being able to cancel payment, the second issue is not being able to access the account, the third issue is that it changed and created a new account and I can no longer access the old one. This is very crafty of someone on how to steal money from people is what it feels like. They are not available to talk on the phone, they do not respond to emails unless they send the same email again and again with zero information on how to solve the problem. I would love to access the old account, return the money and then delete all accounts. Eventually this will bit them in the booty for sure. You can not steal money and not have a consequence. The sender was also told there was nothing they could do unless the receive ( me) can the cancelation of the payment. Isn’t that convenient that I can’t access the account to be able to that. Isn’t it convenient that there was no record of the transactions and they were unable to help. This is over the top rediculous and it’s fraud. Just like the website said if you are asked to give full credit card information its a scam. The sender is reporting it to her bankcredit card for fraud, and I have written reviews on many forms with my bad experience of this company.
