My online account 1 15 was completely hung up by 1 15, but there was no account. 1 15 staff can give an answer?

I used to be like this, but I figured it out later. I don't need to bind my mobile phone number, but I know the password, and then I need to enter a short message for verification, so I can't log in anymore. After the appeal was successful, my account no longer exists. Later, I found that as long as I unlocked my mobile phone, I couldn't log in through my mobile phone number. If the appeal is successful, I will send you a link to my email address, and the SMS will receive a voucher number. You need to enter 1 15 through the link in the received email, then enter the voucher number, and enter the new mobile phone number and mobile phone verification code that need to be bound, so that 1 15 can be reused, and the account number 1 15 also becomes the newly bound mobile phone number.
