I had the worst customer service from customer service rep Gabby. I called in about charges on my account and instead of addressing my concerns she kept asking for payment for the charges I was concerned about. After explaining my concerns she ridiculed me and laughed. She then proceeded to make assumptions and accusations that I will call back again with another excuse next month about charges. Gabby then stated "discounting the account is not a big deal if that's what you want". I again expressed that my concern is the charges not the discount. I want an explanation of the charges in question. Worst service in the 5 years I've had tmobile. That's absolutely intolerable and I will be switching to sprint.
