KWIKOT - Worst Service and Product Policy/Warranty that is not Honoured

Simply... I bought a brand new Kwikot geyser. The plumber informed me when he was installing it that there is fault on the new geyser. We then both called Kwikot KZN and Head office and they refused to replace the geyser with a new one but rather send another plumber of theirs to repair a fault on a brand new geyser. Johan Coetzee from Kwikot HQ also confirmed that it is probably a manufacturing error but still refused on a new replacement. Their first line on their own Warranty states,"Electrolux SA (Pty) Ltd warrants that’s its KWIKOT electric water heater are free from manufacturing defects." The worst service I have ever encountered and I shall be reporting this to the consumer ombud
