Iwyze will tell anything to reject claim

First rejection claim : My built in stove Iwyze reason: the element damaged by the foil I wrapped 5 years ago. I called someone to fixed it , the element was replaced and after he did he told me to cover it with foil cause it keeps the stove clean, I was so astonished by this because Iwyze they will not fix it because of the foil was wrapped to the element. Second rejected claim: I reported lick in my son’s room and mould in his room, the consultant told me that to find someone to look at the roof and go back to them with the outcome. Recently I called the call centre to report the mould has worsened and spreading into my room, Keith who took over from Prudence told me that I should service my room like my car I cannot stay in a house for 20 years with servicing it, he also told me that he will trace the call of other consultant who told me I must find someone to take a look at my roof and call me back. It’s over a week now he hasn’t call me
