Worst customer service I've experienced at a T-Mobile store. Which is a shame, because T-Mobile is an awesome company with amazing coverage! I walked in to add a line, and only one other customer was in the store. The other rep not helping that customer was on his personal cell phone for five minutes, smiling and laughing, completely ignoring me while I stood there waiting. After he got off the phone, he stood there smiling at his phone and continuing to ignore me. Two other reps came in while I stood there and also ignored me, while laughing and talking together. These guys don't seem to take their job seriously. I walked out, and no one tried to stop me. No commission for them.
