Bad Service from Insurance Policy

I have been a client of standard bank for more than 8 year now. I have a home loan with them which include the building insurance. In the past 8 years I have been a client I have never submitted any claim until June 2021, I submitted a claim for a leaking roof which I received a bad service starting with answering of emails they take days to respond to emails. An assessor was sent to my house to check the leaking roof on 4th June 2021 he did everything and even take pictures of the area, the following day I received a call telling me my claim was rejected, the course of the damage is not covered in the policy. I enquire about this and wanted the report that was done by the assessor including the pictures taken but I was not given a response for days and eventual when a response was given I was given a run around service telling me I must wait for the report they need to get it from the builders, it took a week before getting back to me with the report, that was incomplete with no pictures. when I enquire about the picture I was ignored no straight answers was given and no pics were given. To my surprise I receive a call from the builders wanting to come again to my house to take pictures because standard bank indicated the previous ones taken are not clear, so they need to take more pics keep in mind the decision to reject was already made from the previous pics taken and now on the 29 June 2021 the assessor comes again for pics. So I questioned this and reason for asking for more pics these people send me from pillar to post before I could get a response that I was not happy with because they **** about them making a decision based on unclear pics, they even indicated that in the 1st appointment the assessor did not take pics even thou he confirmed and I was at home when he took pics so these people are lying to me. In the report the assessor is even the one telling me that the damages are not covered on my policy so asked how come and assessor be the one making that call. he doesn't even know what my policy covers. I have then since decided to cancel my insurance with them at a lost of all the years i have paid with no arrears or skipped payment not even once. I will not recommend standard back building insurance to anyone they are ******** taking people hard earned money and when its time to pay for claims they tell you the insurance does not cover it. I'm so disappointed in a way my case was handle and not assisted at all. It been over a month dealing with them on this, having sleepless nights over this. I'm so drained emotionally they have no idea of the damage they have done to me. I will never again insure with them. I'm even considering moving my home loan to another bank. They have benefited enough from my money not anymore. They have not proceed my cancelation yet, I'm still waiting because there is a notice of 30 days before cancellation can go through.
