This is the worst customer service ever. First, no way on earth you will get your code within 24 hours. Second, I sent an email to cancel as I ended up going with my service provider to Unlock and what they do is the sneakiest thing ever. They sent me an email saying that the unlock was complete 3min after i email them with refund request so they don't have to refund me. Finally, they stopped replying to my emails.
STAY AWAY! Call your service provider and unlock it with them even though it will cost an extra 25$. This is not a safe site keeping all your credit card info. Beware!
