I sent my IPod Touch for a very Minor screen repair.
I had an email back to say "˜we could not fix your device, our best technicians tried doing everything possible to get your device working again but they were unsuccessful because the damage on your device was too severe'.
This was a very minor screen problem so I know it can be fixed.
They asked me make the outstanding payment so that they can return the device.
I tried to call them to organise this but their telephone was engaged for days and days.
I have reported this company to trading standards and would advise you not to use them!
