What UPS did to me once is a real charmer.
I ordered a bunch of clothes online from one of my favorite places to shop when I lived back home. I basically got an entire wardrobe's worth of stuff, including an expensive leather coat. I knew I'd pay the customs, but the exchange rate and sale was such that it was still a good deal.
Ok, fine, I get my order, and UPS confirms the customs processing with me. They send my order, I get the customs bill and pay it...
Only, the company in question screwed up and sent my a duplicate. Without confirming the customs clearence with me, UPS went ahead and processed it through customs, and it was waiting outside my door with a nice big bill in the hundreds of dollars. They refused to take it back, claiming I signed for it, when I wasn't even home, and neither was my husband.
I called and emailed many times to that company, and they just weren't bothered, not realizing that the free duplicate order actually cost me a bundle. Needless-to-say, it's my last time shopping there, and I still have a brand new leather coat to take over when the old one dies.
