Don't work for them however I have been a customer for seven year.
Six years of great customer service.
Last year merged my wife, SD, and I onto a family plan.
Don't know if it is because they (wife and daughter) got smart phones (LG optimus)... but we have had a bunch of problems.
Also don't know if it is because they (T-Mobile) have been bought out by AT&T.
But yeah... so far this year... not very impressed.
