TERRIBLE EXPERIENCE TRYING TO GET MY BURST GEYSER REPLACED!!!

I reported a burst geyser on Friday 4 December. Plumbers came out and had a look on the same day, confirmed it was a burst geyser and needed to be replaced. Today, 6 days later I am still waiting for a replacement geyser. I have been calling my claims hander Kgomotso daily to complain, but she never returns my calls and never keeps me informed of the progress. She says she will call me back, but never does. i will be holding Miway responsible for the water damage caused to my ceiling and trap door. The service providers ITU Assistance Services have done the exact same thing... tell me they will get back to me and just never do. i arranged to leave work yesterday to meet the plumbers at my house at 3 and they just did not pitch up or call or nothing. i am furious at this point.
