Apparently they reply in 24 hours, but usually less than 12... not! I have sent numerous emails with no response well past the 24 hour time period. Like most of the others on here, they take your money, say they can't unlock the phone, tell you you're getting a refund and then don't give you a refund or respond to emails. I wish I had seen all the reviews before I went with this "company" to unlock my phone...
