BEWARE!! HIGH PRESSURE SALES!! I went in for a new SIM card and was ganged up on by three clicky young glam-dolls. They insulted me in the guise of "saving me money," when a review of the fine print made me think otherwise. After I refused to change to their newest "promo" plan, the room got ice cold and I was told that a SIM card was now $20, even though my son went to a different store a few months ago and got one for free. When I said that even T-Mobile online says a SIM card is $10, the blond manager instructed the witchy one to charge me only $10. I've been screwed over at this store before when I changed to a "promo" plan and ended up screwing myself out of features we all enjoyed. I felt like I was the outcast in high school again as these three girls berated me and insulted me when I told them I didn't understand what I was getting into and just wanted to think things over. I was actually told that the new plan was "just common sense" and that if I wanted to pay more money for the same thing, I could "go right ahead." These were the snottiest group of salespeople I have encountered. I'd complain to T-Mobile, but they don't seem to have a complaint department. DON'T GO TO THIS LOCATION, I've had friendlier and more helpful service at the location inside Chandler Fashion Center.
