Had a missed call from this number, called back but no response. My cell phone number is a new one I just got, but I put it on my USPS package I shipped out today to Africa. If it's a scam, then I think there are some crooks working with USPS, who steal our information and give them to these fraudsters. This is serious bcos I have my address and phone number on the package. Who knows what these crooks may be doing with our info
