Ed, if they've just frozen your account and there's no money there and no money pending, you can close the account and open a new one under the same name with the same bank card and the same email address.
It's the massive loophole in their system. As long as you have closed the previous account you will be able to do this. I just did it last week as they would not unfreeze my account and someone was waiting for payment. They wanted me to go through some long procedure like you. I told them i would not.
At first i opened an account with a different email and removed the card from my first account so that i could put it in the new one. This way i could start making/receiving payments immediately.
I emailed them to tell them i had done this and that their system is flawed but i just did that to get up their nose.
Once you got your new account you just tell whoever it is you're waiting for money from to pay again to the new email address. (if they have sent money to your old one they can cancel it and then pay to your new one)
Once i had sorted out that payment i then completely closed my old account and changed the email on the new account to my regular one.
