Guarantee not honored

On Thursday 3 December my geyser burst, after contacing on Saturday the insurance a plumber was sent out who confirmed the geyser had burst and according to yhe serial is still under guarantee but yhe company closed and was sold over rendering the guarantee void. I spoke to several people at Dialdirect who refer me to the clause that the manufacturer guarantee applies and ad they closed itbis basically my problem. I have requested that they go back on claims history. The geyser was replaced in 2016 vy them with a WE gesyer and I raised concerns at that point that it is a inferior product and not reputable like kwikot that i had in. I was assured that this is a good product and i am covered by the guarentee. Now that the geyser burst i am being told its my problem. I was told i must discuss it with their guarantee department but when transferred they are not available. On Friday 1 December a lady phoned me back and after explaining everything yet again she said she will investigate and get back to me. I am sill waiting. After loosing my job with lockdown i removed several things from cover to save money and geyser damage cover was also removed as i knew i had more than a year guarantee left this would have given me time to find my feet and reinstate later. Is it fair towards your clients for installing a cheaper inferior product gambling with guarantees should a company survive or not and put the risk on the clients shoulders? Insurance industry is supposed to put the client in the position they were in before the loss and while having warm water was part of this installing a interior/not reputable product surely is not fair.

I have waited more than a week trying to get assistance and my next step is now lodging a complaint with the Ombudsman should i not be contacted and assisted.
