I don't need this service now, thank you.
A friend called into see me and he had experienced the same 'unlock Sim-Pin' problem, also.
He told me how to restore the software to 'FACTORY SETTINGS'.
I feel that either you of your online 'experts' should have known the solution, to pass onto me, considering the time you had, on my stated non-urgent status - which i registered in one of my 'chat'-pad texts.
Also, I feel that you did NOT fully understand my original description of the problem. Why do I say that? it's because that I had said that the SIM-card is OK, because I am using that one in my Apple 4S i-phone.
So, the problem was never about the SIM going "BAD" as one of you guys said. It was a simple question of my not knowing how to restore to 'Factory Default Settings'.
I didn't know when I subscribed to your service, but I do know now, because of my friend's knowledge.
I now need a refund of my £28 please.
