What companies have given you excellent customer service?
Last night I had an excellent experience with Amazon customer service. I had ordered a cooling pad, received the wrong size, took steps to replace it, and got another one of the same, wrong size. I called customer service, and they couldn't have handled the situation better. I'm VERY pleased.
I know that there are lots of horror stories out there, but what companies have given you GOOD/GREAT/EXCELLENT customer service?
