Hugh Pickens DOT Com writes "Reuters reports that the high volume of online orders of holiday packages overwhelmed shipping and logistics company UPS delaying the arrival of Christmas presents around the globe and sending angry consumers to social media to vent. The company projected 132 million deliveries last week "and obviously we exceeded that," said UPS spokeswoman Natalie Black without disclosing how many packages had been sent. "For now, UPS is really focused on delivering the remaining packages. You might not see trucks, but people are working." Asked why the company underestimated the volume of air packages it would receive, Black noted that previous severe weather in the Dallas area had already created a backlog. Then came "excess holiday volume" during a compressed time frame, since the period between Thanksgiving and Christmas was shorter than usual this year. Amazon.com responded with an email to affected customers offering shipping refunds and $20 gift cards to compensate. Packages shipped via UPS for Amazon.com by Prime customers, who pay $79 a year for two-day shipping, may be eligible for additional refunds. Amazon's stated policy for missed deliveries is to offer a free one-month extension of Prime. Frustrated consumers took to social media, with some complaining that gifts purchased for their children would not arrive in time to make it under the tree by Christmas morning. '"A lot of these employees keep saying 'It's the weather' or 'It's some kind of a backlog,' said Barry Tesh. 'Well then why, all the way up until the 23rd, were they offering next-day delivery? That guaranteed delivery was 80% of my decision to buy the gift."' However, others on social media urged shoppers to be more appreciative of the delivery company's work during the holiday season. 'While others take vacation and time off in December, remember we aren't allowed ever to be off in December. Ever,' said a 20-year veteran UPS driver on the UPS Facebook page. 'So when you see your family and complain that your package is held up, everyone who moves your package is working and doesn't get the Xmas experience you get, Be thankful for that.'"
