INSURANCE FAILLING TO HELP ME AND POOR SERVICE

I have a complaint regarding the claim I made with Indwe Risk Services last year in May 2024 my geyser busted water was all over the house, the insurance appointed a contactor to replace a new geyser and the other one who came and paint walls and ceiling. Then I called the insurance now in April 2025 that there is a vibration on the geyser when we open taps and there is a lick from the roof the same ceiling painted its roten again as water is licking from the geyser. 2 guyz were sent to my house one is a white guy from Best plumbers who explained that the valve on the newly installed gyser was incorrectly installed and the fault is with the contractor that installed the geyser he left and they sent another plumber by the name of Akani she said the pipe from the geyser that was supposed to spill the water outside was never taken out and the water is liking inside the house, currently my ceiling is damage and the water damaged my kitchen unit. I called and my claim is with Thulane he said to me he doesnt have the record of the previous contactor who fixed the problem, so this should be treated as a new claim. My question is its been hardly a year my geyser was replaced same problem happen again its hardly 12 months, no 2 who should be held responsible as the insurance seem not willing to assist me. my contact ***
