DENVER -- UPS spent the day apologizing to customers and playing catch up with deliveries after many spent Christmas without their gifts under the tree.
After giving drivers the holiday off, UPS delivery trucks were back on the road Thursday, in hopes of making up for lost time.
At the UPS customer center in Denver, some customers opted not to wait for home delivery. Evelyn Rael had been anxiously awaiting a gift from her boyfriend since Saturday.
"It didn't make it to my house," Evelyn said. "So I'm here picking it up today."
Rael was one of many people who got a call from UPS saying her package was at the Customer Center and ready for pick up.
"It is frustrating," Evelyn said. "Because I really want to open my Christmas gift."
It was even more frustrating after Evelyn went into the building only to find that her package still wasn't ready.
"They just told me I had to wait 30-40 minutes," she said.
Brittney Palmero said she's been waiting for more than two weeks for the gifts she ordered for her husband.
"I don't know the words to use. That's how upset I am," said Palmero, who ordered more than four hundred dollars of electronics. "I even paid for the expediate shipping through UPS. I have never received one of those packages."
Though several storms did hamper deliveries in December, UPS has admitted that it's network simply couldn't keep up with the huge flood of packages it received prior to Christmas.
Though it didn't make deliveries on Christmas Day, the company did call in added staff to it's hub in Kentucky in order to help sort packages.
Today the company released a statement saying: "UPS apologizes to both shipping and receiving customers who may have delays... We expect all excess volume to be delivered today or tomorrow."
"I've talked to UPS many times and they keep putting me on hold," Palmero said.
Palmero says she still doesn't know where her gifts are, or when they might be delivered.
"I don't even want to order things off of Amazon any more or anywhere that has to do with UPS," Palmero said.
Evelyn did eventually get her package on Thursday evening, despite twice the expected wait at the customer center.
"Almost an hour, yeah, almost an hour, but I'm patient," she said.
Patience is needed when an overnight package takes over six days to arrive.
"I'm just happy I'm done with it," Palmero said.
