Finally my iPhone is unlocked... But the customer service is pathetic, nobody will reply to our emails and the unlock price is increased even after making full payment. I was feeling like I got trapped as I had already paid £100 and again £25 was asked saying price has been increased, I had no other options neither they replied to my emails for refund, nor they will process on the earlier agreed price.
I would have given 1 star, but now since my iPhone is unlocked, I am giving 2 stars.
