Standardbank Insurance are bad

My geyser went faulty, I lodge a call on Friday 3/7/2015. I didn't get a response from them and phoned them on various occasions to ask them to please attend to the problem. I then found out that the plumber was at the house and said it was a warranty claim and that he cant do it. He said he did tell Standard Bank, which just left it at that, they never contacted me or anybody else. I had to phone again and again, and every time the promise to phone back, which they never did! Today they told me that the problem is the supplier don't have stock. (this is called \passing the buck"). I got hold of the supplier and he said the geyser will be delivered in two or three days time. This will mean that my household will be without warm water for 2 weeks! This is totally unacceptable service! If I didn't phoned"
