Avoid, Avoid, Avoid. Like other people I was taken in by their apparently honest description of what I am paying for, £17.99 to have my phone unlocked. And yes, the next email asks for another £46 79p they are a very dishonest, unscrupulous setup.
I read the reviews on their site, obviously all false, no one will be "delighted" with their rip off scam.
There has to be a way of getting them stopped from scamming the public. I should have gone to the shop where I can get it done for under £20!
