Weakest service

I contacted Standard bank insurance for a claim for my geyser on Thursday morning at 09h22. I was told the service provider will be at my house to inspect and repair the geyser. Well today, Friday, I have made 3 calls so far and on the line with them for over 30 minutes on each call. I was told that they cannot find a service provider to do inspection or repairs. So, now what must I do. No hot water for 3 days already and it is Friday afternoon. Meaning I will not have any hot water for the weekend. I have been with Standard Bank for over 47 years now and had all my mortgages through them. Now that my house is paid up, still paying the insurance, they cannot help me. I think the service that I have received is pathetic and disgusting. To Standard Bank, When are you eventually going to repair my geyser.
