I recently wrote a negative review on the inconsistent, ill-trained customer service I experience at Walmart. In contrast, T-mobile has well trained, very polite, very concerned customer service. When you call, instead of keeping you on hold, they tell you the wait time and will call you back. They are very respectful, If they are talking and you begin talking, they immediately stop and listen to you. I purchased a T-mobile hot spot and with customer's service help, had it up and running in a few hours. Had to call back a few days later because of a web page blockage and experienced the same courteous, professional respectful responses. Walmart needs to take note and hire the people who trained T-mobiles customer service department.
