Because they are bloody muppets and I hate them.
We bought one of their shitty washer/dryers in 2009 and basically it has broken down, on average, about three times per year ever since. As the repairs were costing £40-£50 a pop, we took out a repair cover plan with Hotpoint to cover us for a year at £60 for 12 months.
I asked them after the umpteenth time it broke to just give me a new machine and they were like "urrrr NO"
It's broken down again. The repair man was supposed to be here between 9 and 11. It is now 11.04. I need to go out and do stuff. Does he think I live my life around the times that repairmen arbitrarily decide is the time they are going to turn up? I bet he will be sullen and unapologetic when he does turn up.
I hate them. HATE THEM.
