As per Paypal:
Question : Can I register a credit card on more than one PayPal account?
Answer : No. For your security, you can register a credit card on just one PayPal account at a time. You may, however, register several different credit cards on a single PayPal account.

If your credit card was registered to a different PayPal account, you need to log in to the previous account and remove the card before adding it to your new account. To remove credit cards from your account click Profile at the top of the page and click the Credit/Debit Cards link in the Financial Information column.

SOURCE: My pal pal account has been closed .They owe me

Your paypal account would not have been closed without due cause. It may be worthwhile asking paypal what is going on, as ebay is only acting on that information.

SOURCE: If I purchase an item

Once you purchased the product, an invoice will be sent via ebay from the seller.
Once you check your paypal, you will see an invoice/bill about your purchase product.
