WeChat — Account recovery problem

Address: 13200

Hi, my wechat account had been linked with my old phone number which has expired recently, and i didn't manage to link it with new number as i always log in using wechat id.

The problem is, once i reinstall wechat apps in my phone, i was automatically logged out and can't log in (and also recover my account!).

I had try every possible thing to recover, from the verification from SMS code (of course fail as i didn't manage to link my acc with my new number), then via email. The email is also one thing. It just say that, "successfully change to a new password, which also cannot use it for log in my account. Then, comes to QQ ID recovery method. Also didn't success as i didn't remember my long QQ ID.

After the three steps above are not success, i touched the 'password retrieval' at the bottom. It was so annoying to find out that QQ ID is also required there! I just don't remember my QQ ID and it was like i can't retrieve my account back at all. Then what's the point i'm linking it to my email if i can't retrieve back my account via email?

Please wechat, i'm begging you to recover my wechat account as all the importants contacts are in that account. Please help me. Thank you.
