ABSA Home Insurance - Worst Insurance to have - decline claims without proper due deligence

About 2months ago I claimed from ABSA for my house (building). I claimed for damages that were caused by a storm (Fischer boards fell and leakage on the roof that damaged the ceilings and walls). After weeks and weeks of following up with ABSA I was told my claim has been rejected based on negligence. I then asked for a written communication which I have not received and I was informed that an external assessor will contact me to come assess for the 2nd time (this has not been done). I can not be paying almost R600 month to cover for my house and when I claim its referred to as negligence ( I do not create storms nor paint/renovate the house every year). I do not understand why a 2nd assessor needs to come - I expect all the damages to be paid for without any delays as I will follow all channels that I need to for this issue to be sorted.
