Forest Fitted Kitchens

I've had my Forrest kitchen for about 6 years and suddenly two of the doors have "delaminated". On contacting the company I was first asked if the doors were near any heat, which they aren't but as they are in a kitchen that could have been a possibility! When someone came to have a look he told me it was just like a hob or a fridge breaking down!! It happens apparently!! He said he would order new doors and they would be fitted free of charge, but oh no the doors would not be free of charge they would cost me about £70 to £90 each. According to him the doors are guaranteed for six years but as my kitchen was just over six years old I would have to buy replacements. I asked for a definite price before he placed the order and when another man phoned me back with a price he told me that the doors are only guaranteed for a year but as they buy a lot from the company they sometimes give them 3 - 4 years but never more than that. So the price would be £50 plus VAT each, i.e £120 for the two, and they would fit them free of charge as their way of helping their customers. I think they need to get their story straight. They are definitely not getting any more money from me. I lost all trust in them when they were fitting the kitchen in the first place when they tried to fob me off with an ex-display hob, and I'm pretty sure we got an ex-display tap because that has had to be replaced as well. I would not give them even a one star rating but the form doesn't permit a 0 star rating.
