So i initially paid £17 which i assumed was the cost. But then received an email for £50 which they said was the actual cost and is in their terms and conditions. Just to make you aware it does not take 24hrs but more like 4 days and they also state in the terms they have 30days to unlock. To be honest the email they send to unlock the Samsung was straight forward, but it took far to long and is really expensive. I would advice to go to one of local shops first as they usually charge only £20-£30 to get it done and it is normally done on the same day. I wouldn't use the company again due to the cost and time taken.
