Poor Standard Bank service

I had my solar geyser replaced by Rimitsu CST Enterprises(who also do not seem to know what they are doing) on the 2nd of May 2024 Since then it has been spewing out hot water. I complained to Standard Bank. Nothing has been done since then Finally they refused to pay for the errors mad by their contractor. I must now pay for their poor contracted services They provide the cheapest service available. I was finally told to contact the ombudsman should i wish to proceed futher. What a poor service on the part of Standard Bank, a called reputable bank. Their services are disgusting.
