Got my gmail disabled, how to solve it?

[hacxx]

Hi,

My gmail account has been disabled, i use it to register on forums, write and answer emails, manage a mailing list and manage cse.

Does anyone know how to fix this?

I tried the recovery feature and my phone number can not be verified (used multiple times).
Using another number gives the same error.

Thanks

This phone number can't be used for verification, or there were too many unsuccessful attempts. Use another phone number or try again later.
