Bad service

On 10th of October 2021 I claimed for a ****** laptop that I insured with hollard through Edgar's. Then on the 11th of October 2021 they send an excess fee which was paid on the same day. Since then I have been calling them every second day and they have been promising me the world. I tried to get hold their superiors but they are also no where to be found. The sales consultants kept on promising me that someone higher than them will come back to me, but no one even bothered to do so. But every month for the past three years they have been getting their money I never even skipped a single month. Till today I'm still waiting for someone to come back to me. Most of the time I'm working from home and I rely on that laptop to complete my work duties.
