Incredible Coruption

Bought an Acer laptop for my daughter for varsity in December 2014, unit has continuously failed with blue screen and unresponsive mouse pad, Cradlestone keep on telling me its fixed but it still doesn't work, so 6 months down the line my daughter has had no use of her laptop which is still in the possession of Cradlestone or Acer who knows ??? The unit has also been scratched albeit a minor scratch its brand new and whist in Incredible *******ions care it has been damaged. Your service sucks and I demand a full refund of this unit
