I have purchase an unlocking code from these guys but did not receive it. Every time I contacted CellUnlocker customer service I heard only lies, they said they were working on it and needed some extra time. Three weeks later I contacted them again and they said that my code was finally ready. So I received my code but it was not working. They claimed there was nothing wrong with it and asked me to try again. I tried and nothing. Asked for a refund and they refused. Cheaters! I will report these guys and will post negative reviews about them everywhere I can! Avoid!
