Useless Discovery Insurance

Hi im having endless problems with Discovery Insurance from the internal assessors giving wrong feed back and lying about your claim to worker's delaying claims for weeks trying not to pay out. I jave send more than 7 emails and more than 10 phone call with no response from them. Discovery is really useless and just take your money. My geyser and pipes and roof is damaged but they only want to pay for the geyser and not the pipes amd the roof now t i must wait 2 months for an internal assessor to come out an look at the problem. Looking for a reliable insurance cancelling this month
