A package was supposed to be delivered to me but I was not home to sign the delivery, so they gave me a door tag number with a barcode. I downloaded this app and scanned the barcode like I was instructed to, and it told me that the number was not found. I tried the FedEx website, and it told me the same thing. I tried the other option which was to text them along with the door tag number, and I got the same response. Communication is just bad. Now I have no idea where my package is. Are they going to try again or are they waiting for me to pick it up at a nearby FedEx store?
