They are so unprofessional! They never once answered the phone and I called multiple times and at all different times. The only response I received was email and it took them DAYS to reply back. On top of all of that the code didn't work and when I told them that, they blamed it on me, argued with me and refused to refund me my money, even though their website says "Money back guaranteed". I have never before received such bad customer service and I wish I could rate them lower than one star. You will have better luck calling your carrier and having them unlock your phone for FREE just like I did!
