Standard Bank Insurance de*****ing its customers

Standard bank Insurance de*****s customers I have a claim for wall fencing with them claim no:20/003463 , I did not build the fence wall I bought it with the house and I was quoted by Standard bank for insurance and the evaluator came and assessed the house for insurance, Standard bank is now telling me that the wall is not build according to SANAS because there were no pillars, what I don't understand is how they did not know that the wall is not build according to SANS at the time? only at the time of a claim I am told that, five years later after collecting payments every month without fail, it is even stipulated as covered on the insurance certificate for the wall fencing, their internal incompetencies are now becoming my problem as they don't want to take responsibility Their service is very dreadful, I would not recommend it to anyone, I seek for a reputable insurance that take care of their customers when in need that's the whole point of having insurance. I ended up fixing my wall for security reason but had to take a loan to do that, they really abuse their customersSE, its institutions like this that should not be supported for they take their customers for a ride and leave them in deep debts.
