Absolutely disgusted with the rip off "know how" scam. I have had this service for a number of years. When I needed it I had to wait a week for an engineer to come out, by which time I had lost a freezer full of food. The freezer promptly broke down again and this time they can get around to me in four days. It doesn't take a great intellect to realise that people pay for this service to receive promt attention when disaster strikes, not to wait a week to get a freezer mended. I believe that you have to have an engineer out four times before the appliance is replaced Don't bother trying to get hold of know how by phone, as you end up being passed from one person to another and ending up no further on than when you started. One particularly spiteful phone operative pretended that he didn't know what I was talking about before saying that I had asked him the same question five times and that he couldn't help and refused to put me through to his manager. Great customer service Currys, I for one will never buy anything else from you, and will inform everyone I can about about your dirty tricks.
