I have two Tmobile accounts associated with the same mobile number. This is due to the issue with Tmobile not able to port the number from their old system to the new system correctly. Now I am unable to login to my online Tmobile account. Whenever I try to signup it shows that the phone number provided is not correct. If I try to link the phone number with an existing online account by providing the verification code from SMS it still provides the same error that the phone number entered is incorrect.
