Household insurance claim

My name is Boitumelo Moloi, and i have a household insurance with Dotsure. I have logged in a claim with them on the 16/01/24 for my wall fence which had fallen as a result of heavy rain storms experienced early this year. My consultant informed me i can go on with the repairs as i explained to them that it posed a safety risk. She then required me to furnish her with photos/sketches before and after the repairs for the processing of the claim, which i did. I received a letter from them two days ago informing me my claim has been rejected because there was no assessment done on the wall before the repairs. This came as a complete shock and surprise that it had to be mentioned at this stage and as a main reason for rejection. Dotsure was grossly unfair to me.
