E-mail address is basically <surname>.<initials>@gmail.com so also no.
I see you are using gmail, did you check your spam folder?
I also agree that BT Games website is pathetic. Take 2's website is much better. I don't buy that many games from BT, but when I do and I want to pay, they always have issues with their system (being extremely slow or losing connection) and I always get the same answer, they are busy updating the system or they tried to update but had to go back to the old system. (Tygervalley branch).
One thing that really pisses me off, when you stand in the queue to buy something, the staff feels it is necessary to have a 10 minute discussion with the client currently paying for their game (maybe not 10 minutes, but it feels like it). They don't have to be rude to the client, just say 'sorry I cannot chat now I need to attend to the other clients'.
