Absurd

I have a home insurance with Absa and i haven't missed a premium...I've been with Absa insurance for more than 2 years now...since moving in our new home.On the 19th of November i lodged a claim regarding my Bath Tub which has cracked and Absa sent their preferred plumbing company to take pictures of the Bath and do the inspection the same day...yet they rejected my claim....of which i was the one calling trying to find out what was happening with my claim....I spoke to one of their consultant and he told me that the report from the plumbers was not clear so he had to take the matter to Absa's investigation team..then i should wait for the feedback in less than 48 hours...i waited for another 78 hours...then on monday the 2nd of December i phoned again to find out...they referred me to another consultant...and then She told me the claim has been rejected due to unforeseen circumstances and my Bath tub had no full support underneath and they do not cover for defective workmanship,of which i don't understand because when we took the insurance no inspection was done....we've been using that Bath Tub and so was the previous owner's of the house...how the hell should we have an insurance and yet they reject it...I'm so extremely disappointed...claim number (***)
