SELLING GOODS THAT IS NOT WORKING

We bought a Bosch Gas water heater from Western Gas. We had to purchase additional goods which included a cover for the geyser when we complaint to Western Gas that the geyser is not working properly. After this was done, the geyser was still not operating as promised by Bosch. We now queried it with Bosch and they advised us that it will take 48 hours to address our problem. Thus meaning we look at only Monday or later. Sitting without hot water for the weekend. I do not think this is fair. We purchased a product from you and it is not operating as it should. We already paid for this product and your service towards customers that already paid is unacceptable. I have lost all faith in your products and will advise anyone interested in buying Bosch products accordingly. The fact that you can only attend to our complaint in 48 hours gives me the impression that you have so many complaints before me that you need to attend too. It does not say a lot about your products, does it?
