Need some advice on how to deal with this situation... Last week my family switched our 4 lines to T-Mobile through their "Uncarrier" deal. We traded in our 4 AT&T iPhones and were given $620 to put towards T-Mobile phones. We chose 4 T-Mobile iPhones. We subsequently had terrible service around Reno and my iPhone 5S could not get service at our home. After trying another 5S, I still could not get service around the house, and the store said my only other choice would be to choose an Android phone. Consequently, I returned our phones to T-Mobile and ported our numbers back to AT&T. T-Mobile is now telling me that I lost the $620.
