I used this service and got the same response 24 hrs later stating unable to provide my unlock code, you will receive a full refund. However unlike the other persons stated here i got a full refund promptly the next day. You need to go to their site and hit their contact button and send them a email requesting a refund. If you don't do this you will not receive one. this is written in their terms and conditions.
I would not use them again as another service on Ebay was able to send me a code within 12 hrs for just a £1 more. And hey presto it also worked.
