I had a letter delivery that had to be delivered within 24 hours to my son, a US Marine, stationed in CA. It was TIME SENSITIVE. The cost was $43.00 and it took 2 days to get there instead of overnight. I wrote to the customer service office in Atlanta, GA to ask for a refund because the shipment was guaranteed next day. The least they could have done was refunded me the difference for a 2 day delivery. Here's the kicker...UPS did call me and promised me a refund for their mistake and then never came through with the money. I even wrote a second time and never heard from them again. This failed delivery was in January of 2011. NEVER AGAIN will I rely on their shipments. The US Post Office is less than half that price and is located directly across the street that the UPS Service Center. Shame on them for not supporting our country's troops.
