Geyser claim

Sitting with a burst Geyser for two days. Had a rainstorm inside our home. Reported the problem to ABSA 2 days ago and they sent out a plumber from Hutton East. The guy came out and saw the leakage and also saw the “rain” inside our home however he said the geyser is still under manufacture warranty. He left with no resolution. Day2 many unsuccessful attempts to contact HEAT TECH GEYSERS so we contacted ABSA who then contacted HEAT TECH GEYSERS. They sent out someone. We were told our geyser had burst. He left still with no resolution!!!!! Day3 nothing!!! How many more says do we go without hot water is any mans guess. I have a damaged ceiling a damaged wall and lifting floors. And still no resolution!!!!!
