Hey was wondering if anyone could shed some light on this. I started to apply online for a nationwide account, it said I had to register first, so I typed in my memorable dates etc, and then started to apply for a flex account. Half way through I had to stop because I didn't have the info next to me, it then said it had saved my application and that I could return at any time to complete it, but I have no idea how to do this! When I try to log in it asks for a customer number, pass code etc but I don't have one! Do they send this number in the post?
