Absa exploitation on home insurance

My mother Mrs TY Ngxumza who has house insurance has been exploited by Absa house insurance. In 2019 our house caught fire, she claimed and Absa sent contactors to renovate, but they replaced the damaged good with cheap material which is now in less 2 year is spoiling and Absa never sent assestors to check the work done.my mother has chronicle conditions and is not fluent in English they used this against her by not following up. My mother installed very expensive material so what has been replaced is cheap material alot of the damage was never fixed. I had to travel back to EC to try get this sorted we contacted Absa and we were promised a call back after very disrespectful questioning and disregard. We are upset and disgusted by this treatment and request immediate assistance
