Have to agree with you Nige.
My laptop is a DEll and fortunately no problems.
But the lad had a desktop from them a couple of years ago. He also had the extended warranty on it. Within 6 months of having the machine the graphics card went kaputt. Not a problem gauranteed repair, but oh no it took numerous calls to the Indian call centre as your friend said being transferred from one person to another.they even gave us a number to try from their alleged help desk which you could only access by entering your credit card details first(which I didn't do).
In the end after 4 days of numerous unreturned phone calls and being messed about I rang back the original number threatening them with breach of contract. The computer was collected the next day and returned fixed within 48hrs. Why they couldn't have done it to start with is beyond me.The customer service is appalling.
A few weeks later i was contacted by one of their representatives who wanted my views on their customer service. So they got it
Needless to say I shall not be giving them any further business.
