Problems with linking my internet phone number to my t-mobile ID

Same problem here, t-mobile doesn't give me online access to my account.  Even though I have a t-mobile phone number associated with a syncup drive device, obviously it cannot receive a confirmation code.  I was told by the support (after hours of talking to multiple people), that in order to change anything in the account I'd have to travel to T-mobile authorized center (1 hour drive for me) and present my driver id to them.   This arrangement is a violation of the paperless agreement and probably some other user agreements.  I don't have energy to fight it, I'm just trying to cancel the service and account, which is not easy, considering all above.
