I hate UPS, they screwed up every single of the 4 deliveries they attempted with me. Never had a single problem with USPS, they're cheaper and almost just as fast!
I had a christmas present delivered UPS and one of my neighbors anonymously signed for it signing another neighbor's name. The drivers aren't supposed to do that but this lazy prick did, and some dick stole my present! I'm working with the retailer to have the charge reversed but it's taking a while.
