T-mobile - I Had a Problem, and They Fixed It Quick
HTC One - Compliment
NOVI, MICHIGAN -- I purchased a brand new mobile phone from a Tmobile store in Novi MI. The HTC phone is awesome, but the one I purchased had a defect in the headphone jack. It simply would not recognize headphones. So a couple weeks after I figured this out I took it to the store, and told them about the issue. They tested it, admitted the issue. Fully expecting to be told I'd get a refurb in the mail in a couple weeks, I was quite shocked when they came out of the back room with a brand new HTC one sealed in box. The whole process was extremely quick, and I was very impressed.
I will admit tmobiles telephone customer service is subbbbbbpar at best, and the coverage isn't great in rural areas. But overall I'm very pleased I switched from Verizon. Saving a ton.
