Account problem

Hello,I believe my Blizzard account may have been stolen or disconnected from my email address.I always used to log in through Google with this same email, but recently I was unable to access my account. What seems very strange is that when I tried creating a new account using the same email address, the system allowed me to do it normally, as if my previous account no longer existed.I am concerned that someone may have changed the account details or removed my email from the original account.I also still have email confirmations and purchase receipts for games bought on that original account, which can help prove ownership.Please help me recover my original account and verify what happened.Thank you.

Please.dont sending me a link to help from website. I tried all options
