Another eBay question...

[DarrenX33]

Sold a fairly cheap item on eBay. This kinda sounds like a scam. This buyer won my item on Jan 25. I shipped the item the next day using USPS Priority. On the 30th the buyer was asking me to provide a tracking number because the item wasn't received yet:

"Dear xxx, Hi. I wanted to know if the package has already been sent to my address because I have not provided tracking number. Regards. - yyy"

I mentioned that I had already shipped it and it should be there soon. I did not mention that I had no tracking number(I know, my mistake), which I actually didn't get. Now on Feb 12th I received another message from the buyer:

"I haven't received my item yet, can you give the tracking number."

I notice something strange, the buyer left me positive feedback on Feb 5th. Even though they are claiming they didn't receive the package?? This particular buyer also has 7 transactions? Of course, now he wants his $ back. Sound suspicious???
