Just state in your mail that you are unable to remove any bank account because there is no option to remove it.
Well, today I got the following message from paypal :
Were sorry, but we cannot restore full access to your account until we
receive additional information. Please provide a copy of each of the
following items:

Please describe in detail what services or merchandise was provided for the
payment(s) you have received using your PayPal account. Please provide
any supporting documentation and invoices if applicable.

Also, you might want to have your Buyer's contact PayPal to verify
transactions made to you.
Can you please suggest me what to do? There is no document proofs for the money that I received so far from any forums. Then how can I submit that documents to that damn paypal? I have right now $20 in my account.
