EA covered my account privately!

I switched between two accounts at 0:14 a.m. on April 21. Both accounts have been registered for three to four years. One is bound to my Game Center account, and the other is bound to my Apple ID. I switched between the associated accounts in the game. In the past three to four years, I switched between these two accounts without any problems. However, in the early morning of the 21st, the game crashed when switching from the Apple ID account to the Game Center account. Because it was very late, I needed to get up early the next day, so I went to bed without paying attention. But in the early morning of the 23rd, my login account showed that the login was G Ame Center account, but the game account has become the account of my Apple ID, that is, the server overwritten my Game Center bound account without my knowledge and confirmation, so I can't log in to my Game Cen now. Ter account number. I went to EA Help to ask for help, but either they told me that I had a problem switching my account and the account was covered, or they said that they helped me find the account. As a result, I did register a new account and told me that the problem had been solved.
