Insurance from hell

Details of Complaint: On the 19th Dec 2018 the ceiling at the above mentioned property fell off in the lounge. A call from as made to the insurance and the details were given. And two days later on the 21 December 2018 an assessor was send through and did the assessment and told us that he will submit the report on Monday. Two weeks down nothing was communicated to us tell I made a call on the 2nd of January 2019, and only then I was told that the claim was rejected due to the cause is not related to hail storm or water burst pipes nor fire. Which I find very dustbing cause my policy is comprehensive cover. With all the interventions I’ve tried they still declined my claim.
