As no-one here knows what you have won it's hard to advise you.
Why would you expect the seller to contact you? (Unless perhaps it's an item to be collected.)
Normally you win an auction, and pay straight away through eBay's checkout. EBay sends you a confirmation message. There's no need for the seller to contact you.
You've been a member for 10 years, so you're not a newbie. What is worrying you about this sale?
