Nedbank insurance disgusting.

On the 7th of March 2019 I logged a claim with Nedbank Insurance. I reside in Mitchell's Plain Cape town and we experienced a violent thunder storm that week the wind was extreme and not blowing in the usual direction I could actually hear how my tiles on the roof was lifting. To no surprise water got in and damaged my builtin cupboards and laminated floor. Nedbank appointed 2 service providers one for the roof and one to check the Interior damage. The 12th the guy of the roof was at my property and said he dont see any damage. I accepted this as I knew the tiles just lifted and water got in. The 13th the guy of the cupboards phoned me and told me he can see water damage and would take a few days to get the report to Nedbank his name was Keagen Bryn. Then Nedbank phoned me and a lady by the name of Jade said she was appointing an Independent assessor to come have a look at property. This is when the nightmare started well his Name was Paul. He then after a whole couple of days went to my house and said he sees no damage to the cupboards, floors and paint. He submitted his report and most likely convinced Keagan to also tell him there was no damages after Keagan had already told me there was damages and he could actually feel the wetness on the floor and Inside the wardrobe. Nedbank phoned me today the 19th March 2 weeks afterwards just to tell me that they wont be covering and that its wear and tear. I even sent them pics of the damage. They did not entertain or listen to me at all. I dont know what to do I need answers from them. This insurance blokes are a bunch ******* honestly.
