Poor Discovery claims services

Discovery replaced my broken solar geyser on my roof. A few weeks later it started leaking. The plumber sent out said Electrolux who supp**** the equipment must come replace a faulty valve as it is under warranty. Electrolux refused to get on to the roof to do the repairs due to safety issues and insisted that the plumber must assist. I had to arrange for the plumber to meet the electrician on site, but Discovery would not provide me with the plumber's contact details. 3 Friday's ago at 16h30 I received a call that the plumber is on his way and that I must get Electrolux on site. I was not at home and asked that we try again the following Tuesday when I will be at home. Suddenly I received a claim closure notification. Since then I have had zero response to any emails asking for the claim not to be closed but for the matter to be resolved. And this is the second time in a matter of months that this happen. Discovery is quick to take your money but not keen to resolve the problem. Wonder who is going to cover the damage abused by the leaking valve......
