An eBay question.

So, made my first purchase of an item from eBay on Tuesday. The person had 100% positive feedback and nothign looked odd. Now, I paid for the item, the payment went through etc. I came back online today, incase he had got in contact with me, but, he had took the ad down, and there was now no receipt of the purchase of the product in my account as a result. I still have the receipt thing on my paypal, so I have messaged the seller there now, to see whats up.

So I'm wondering, has this person tricked me, or did he take the ad down as I had bought it (he had more than one of the item so I'm suspicious). It's not a huge amount of money, but it still doesn't seem to be a pleasant site if I have indeed been fooled on my first try!

Thanks for any input/ideas people put forward.
