How do I have an unpaid case number removed from my account as I have actually paid for the item?

[old*goldj*]

I purchased some jewellery from a seller. They claim not to have received payment and therefore have not sent the item to me. They also have placed an unpaid case against my account which could mean suspension from trading. I have emailed the seller that I have paid and have paypal reference number on my statemants to show this. Awaiting their reply and investigation butI really want the unpaid case item removed from my account. How do I get this done. How do I notify Ebay.

Thanks if you can assist.
