I bought a Samsung Galaxy phone from this T Mobile store inside Arizona Mills mall. When the phone ran out of memory a few weeks later I tried to buy an expansion card but was told that the electronics were damaged and would not read it. I tried to take my phone back and Victor, the on duty manager, refused to stand by his product. He did not refund my phone, try to fix my phone, or offer me a new phone. I am left with a worthless phone that I just paid for. T Mobile does not stand by their products and I would recommend not spending money with these people.
