Worst experience with insurance company

I submitted a claim over 2 months ago for a collapsed ceiling after a damaging rain storm. It has been the worst experience ever dealing with this insurance company. They don’t reply to any of my emails and never return phone calls as promised. There has been no transparency during this whole process and I am no closer to being able to fix my ceiling than I was 2 months ago. I have now been waiting 2 weeks for a 2nd internal assessor to assess the damage after they placed the quote that the first assessor that they assigned to my claim under investigation. I have even contacted the ombudsman to assist, yet no response from anyone at the company. Don’t ever make use of this company for building insurance. It is a nightmare dealing with them.
