So I have 'Won' a bid on E-Bay The final price is confirmed. Pain Pal came up with my account. With a different card ending number [possibly a card discontinued two years ago] Entered my current card number. Pain Pal said this card is on another account. And so we go around a closed loop. Tried to contact them- but it too is a closed loop. So start a new account. Enter card number Pain Pal says This card is already in use on another account.
How do I get out of the loop I have only the one card.
Not much help to you, but I had exactly the same problem with PayPal/E-Bay when I renewed my card a couple of years ago.

I tried for several months, in the end I gave up and have never used or attempted to use PayPal again. I
I'm sure that thousands of us have updated our card details without any grief.
But I would be slightly worried if PayPay/eBay says, effectively, that someone is already using that card number. I would check my account with my card provider, to make sure there's no unexpected transactions; and I would then maybe get them to issue me with another new card, just to make sure.
