Hi, I recently purchased a pair of jeans off SuFu suparmarket. Upon finalizing the deal, I paid promptly and seller says he will ship them out today and update me with tracking. So I was ok with that, but 24hrs later, i still didnt receive a tracking number from him, so i PMed him again. I got a reply from him about 20 hrs that I will get shipping number after he gets back home. Time past, i waited, and i got the tracking number, but the thing is, using USPS website gives me "Delivery Status Information is not available for your item via this website. A return receipt after mailing may be available through your local Post Office. " And even trying EMS tracking site, it says.. "N/A We could not find this Tracking Number in our system. N/A" tracking number begins with CX and ends with CA eg. ( CXxxxxxxxxxCA), if anyone is familiar with it, please advice. Seller says he is shipping from N.America. I have purchased through the supermarket a few times, and this is the first time encountering such issues. So im not too sure if im being paranoid.
