They have an Advertising Standards Authority ruling Against them! They (Direct Unlocks or AppleiPhoneUnlocks - same firm) claim to unlock in 24 hours from £14.99. They charge £17.99 and after 24 hours ask for another £32 which they say was made clear earlier. That's not true and I have the screenshots to prove it! I had to send good money after bad as I was away and needed the unlock. So it costs 3 times their advertised price and takes at least 3 times as long. Why they can still trade with an ASA ruling (25/07/18) against them I don't know. Here's the ruling: https://www.asa.org.uk/rulings/direct-unlocks-a18-447541.html
