I purchased two new lines from T-Mobile. One of the phones was not working when I received it. I paid full price for the phone upfront when I opened the new line. I received the phone the next day. The phone would not hold a charge and was overheating. I called T-Mobile and was told that I have purchase the same phone again then send the defective phone back to them and wait 7 to 10 business days before I will receive a refund on the defective device. Which I feel is not right, being that before I could even receive the phone I had to pay for it upfront not wait until I receive the phone then pay T-Mobile 7 to 10 business days later. If I had of known T-Mobile did business this way I would have never brought my lines over to this company. Buyer beware!
