Unacceptable Claim rejection

I am extremely disappointed in the manner my claim was and still is handled.... after he severe storm we had in September 2023 my place was flooded downstairs and ever since I laid a claim for the damages there was a back and forth from the insurer (approx. 2months later) trying to find any excuse to not proceed with the claim. Not only did I battle with their unprofessional assessors that took days to come to site... There was no follow up from the insurer as well as a statement by them proclaiming without tests, engineering reports or any other evidence that my place was structurally not sound " Defective workmanship". The findings arrived via email even before the assessor was out to site. After many, many emails this ordeal still continues. How many clients has fallen victim to this?? I WOULD NEVER RECOMMEND HOMEOWNERS to insure with Bettersure....
