Basically what KK said. If they ask for further information, reiterate the fact you have all original information necessary for the account to be verified. Sometimes you may come across an asshole CSR who simply won't budge. That's your cue to try again for another CSR. Ultimately, CSR's deal with accounts. If you can verify the account, they really do not care about what you do to it, in terms of changing the information. Now, if you start blabbering about nonsense things they may become suspicious. You only answer the questions they ask, no more, no less straight to the point to a T. Mind you, think of a buddy system. The logs are recorded, they're being watched. You scratch their back, they scratch yours. Make it seem all legitimate, no harm no foul.
