I was initially interested in the Essentials 55 plan for $40/month with auto bill pay. The sales representative showed me, in writing, how I could get many more features, plus a free phone, for $55/month (via monthly reduction of the cost of the phone for 24 months), with the Go5G 55 plan. After signing up for the more costly plan, I learned that some of the features I had been promised were not included in that plan; they were only available on the Go5G Plus 55 plan, which would cost $70/month. I went back to the retail store three times, spoke with the sales rep and the store manager, who both assured me they would "fix" the problem. I later found out they had changed my plan to Go5G Plus 55 without my permission. I than phoned T-Mobile and spoke with two individuals (one being a manager) and was told the only thing they could do for me was to switch me back to the Go5G 55 plan, without the previously promised features. I have not been using T-Mobile long enough to comment on the wireless service.
