Unhappy service by Kwikot Pty Ltd

I am struggling to get my kwikot geyser replaced which burst last Thursday night, 17 August 2023.

The claim was rejected by SA Homeloans (claim number CL***) as the geyser was within the warranty period an needs to be replaced by Kwikot.

The reference with Kwikot is *** who after i enquired with them today via their customer care number that it is a second replacement and the warranty is therefore not valid and they will not do the replacement I am sinxe struggling without warm water and can't get a positive response from SA Homeloans Insurance.
