Auto and General declined my claim during UKZN floods

I would like to report this insurance, I took Auto and General through Nedbank during UKZN floods my cottage house was also affected by the floods, I joint this policy in 2018 full 5yrs without claiming to them no cash back nothing ,they sent assessor to check damages, after that the company that was going to fix damages was also sent for quotation, I was communicating by consultant lady saying next week they are coming to fix your house ,they dragged the claim almost full one month saying the company that is going to help me is delaying ,I kept on pushing them up until the lady by claim department told me that they declined my claim due to patches that they discover in my roof which shows them that the roof was already leaking very stupid reason I have decided to hand over this matter into my lawyer I am not going to leave this matter as I strongly believe that they were supposed to fix the damages !!!
