I would be very wary of this. The company do unlock your phone and provide a good service but a couple of days later, after receiving £10 back for leaving a positive review, my card was hacked and someone tried to take a lot of money out. I also got a phone call pretending to be my bank and offering to sort it out. When I finally did sort it out through the bank, they asked if I had used any unusual websites. This was the only one. You give them your bank details and phone number. So beware!
