Poor service and treatment from Hollard.

I have requested a claim with Hollard, back in November 2019. I had an assessor come out about 2/3 weeks after, and then never heard anything again. I have wrote to them countless times, expressing my concerns and essentially just looking for any update to let me know what is happening with my claim. I eventually logged a request with the complaints department on January 28th, who then advised someone would contact me within 2 working days. Still no contact at all. This has been an extremely poor service offered by them.
