Access account

Good Evening one and all, i've had trouble since i took my contract out. The previous contract was in my wife's name but she wasn't comfortable phoning Virgin up whenever we had a problem so i said to end her contract and that we could take one out in my name because i've got no problem phoning up to sort issues out. 

We visited a nearby O2 store and took the new contract out and were told that using the same email address for my account as we had used for my wifes' account wouldn't be a problem. This proved to not be the case, after 10 phone calls across a two week period we thought the matter had been resolved but still had problems accessing the account and when i can access the account the greeting is welcome back, Kerry!, the same as the greeting on the virgin media app and VM connect. 

In order to access my account i put my email address in which takes me from the sign in or register for Virgin Media O2  screen to the Enter your password screen where the email is slightly different from the previous screen, its changed from co*******hn@aol.com to co*******hn@aool.com so when i enter my password it says that the password is wrong and gives me a limited number of attempts to enter the right details which wont work because the email is different on the second screen, therefore i have to verify it another way which is a pain in the backside.

The fact that the account also says Welcome back, Kerry is also wrong as the account is in my name as are the bank details, surely something can be done about this. I have additional issues but will add them to other forums, sorry about the long post and if you've reached this far, well done.
