Giving credit when credit is due, I just want to give a big thank you to T-Mobile's customer service: on the phone and with their servuce reps in-store!
I was experiencing problems with my six month old T-Mobile Dash (HTC Excalibur S620). When I thought it was a battery issue, I went to the T-Mobile store in Greenwich Village and got a replacement battery - FREE!
When it proved to be more than a battery issue, I called T-Mobile customer service and after explaining the issue, they are sending me a replacement Dash! So thank you T-Mobile!
