I had a similar problem so appreciate how frustrating it is. I emailed both ebay and paypal with pathetic type begging letters asking to speak to a person. They initially just sent me the same instructions that had appeared on the screen when the details failed, so... you send them back their own instructions saying 'this is a genuine problem and I need help otherwise I wouldn't have contacted you, please read my mail!'. It prompts them to read your email and you will hopefully get some form of sense out of them, though for me it meant I had to give bank details and wait a week for them to verify it. Sadly, they then badger you to fill in some customer feed back form, as if they have done you some sort of a favour. Good luck.
