Disgusting service by Standard Bank

I have registered a claim with Standard Bank Insurance last year (2018) for a burst pipe in the bathroom wall. They replaced the pipe. However the hot water in both the taps stopped flowing as soon as they replaced the pipes. I contacted Standard Bank and they did send out a useless group of plumbers who said that my taps are too old and need replacing. I then contacted three other plumbers and they said that the pipes were blocked when they were replaced. I do not receive any hot water in my bath. No help from Standard Bank. It is most disgusting and horrifying.
