Gap sucks/trash service

Zero rating for both indwe and GAP. Made a claim about 2 or 3 years ago about a geyser fault, they appointed a plumber that had it replaced (gap apparently HAD THE GEYSER REPLACED ) and now less than 5 years later I’m been given the run around cause the said geyser is apparently ‘burst’ and don’t know who to talk to and not getting the help that I need FFS. Spoke to the manufacturer (GAP) and they’re telling me they’re waiting for photos from insurance (indwe) and the said insurance (indwe) is telling me stories (I have to find out more information from the manufacturer), I’m stuck between two companies not knowing who should take responsibility for this repair or replacement. Indwe is just unreliable when it comes to customer service shame
