Hotpoint RLA54 Fridge

We purchased this together with the freezer in October 2006 In Feb 2008 (14 months ) the fridge started to freeze produce in the salad trays and was extremely cold elsewhere despite turning the controls down to 1 it had no effect After paying £150 over ten months repair man attended and change the thermostat Repair man came again but decided that it could not be fixed. When we were sold the breakdown cover we were told that if it could not be fixed then we would be given a new machine. Don''''t you believe it. The cover has been cancelled and the payments stopped. The repair man who was excellent spoke to the technician and help desk who agreed that the phial tube was out of position and not repairable. As the machine has been in situ and not moved then this must be a design or manufacturing fault, but as out of guarantee not interested. Only good thing is that this model is not in production any more, I wonder why. This product is not of merchantable quality
