Poor service and support

I was contacted to Ooba insure since I had purchased my home 7 years ago. After the recent heavy storm I had some danage to boundary wall and roof leak. The assessor was sent 2 weeks after I lodged my claim after various follow ups and only 4 weeks later they gave me outcome it was declined due to workmanship issues. They stated if I want to appeal decision I should get my own assessor at my own cost. The communication was not forthcoming and I had to expedite claim via various emails and calls to no value. Its the second experience where they merely respond poor workmanship. Even after I provided evidence that the root cause was not as they described they refused to assist. For seven years I had no problem then suddenly it becomes workmanship issue. I immediately cancelled my insurance and made my necessary repairs at minimal cost. Another thing they are contracted with guardrisk and give you the run around and dodge accountability.
