I purchased some shirts for my boyfriend and paid for them and the seller emailed me said they had shipped and sent me a tracking number for usps and said it would not show up for up to 10 days. It has been over 10 days and it still does not show up as a valid tracking number on the usps site. I also see that eBay has suspended his accounts after I paid. He told me I would get my shirts and the tracking number would show up any day but I am not sure if I shoud believe him. The tracking number looks different from the other tracking numbers that the other sellers gave me for usps so I asked him to give me my tracking number again. Should I file a claim?
