Impossible to get Iwyze to work

I called Iwyze for a leaking water pipe in my roof. The leaking pipe caused ceiling damage. I think this was in the last week of March 2020, just when lockdown was introduced. Iwyze sent a plumber and the leaking pipe was sealed. Iwyze promised me that part two of that claim would be the fixing of the ceiling damage. During that first month of hard lockdown (April) Iwyze said contractors could not come out to fix the ceiling. In May 2020 I started to follow up with Iwyze with no success. Every time I call I get put through from pillar to post with no success. I try at least once a week to call. I tried to register the claim online, also with no success. I used the call-me-back option several times. Once I was actually called back but the operator could not assist and the call was cut. My ceiling is collapsing and I find it so far impossible to get Iwyze to send a contractor for repairs.
