I shipped 2 packages with UPS, one on 12/05 and one on 12/08. Both had initial scans & have shown they were supposed to be delivered for the last 2 days on their tracking tool. Today both are missing, and I have to go to the place I shipped to initiate a search. I cannot believe that just my 2 packages are the only 2 issues with them. Possible internal problem, possible short here??? I just know I will never ship with them again.
