Poor non existent communication and service

I have registered a claim on the 28th of June 2023 for a burst water pipe in my home. By this time I had already fixed the pipe and furnished Momentum with two independent quotes with regards to the plumbing work and the damages to the kitchen cupboards. The claim process was painless and the assessor was appointed. By 4 July I had to enquire about when the assessor was coming out. Momentum then subsequently appointed a plumber to come and fix the pipe (fixed already) I had to explain to them that I do not need a plumber but the assessor, nevertheless, the plumber came out and supp**** Momentum with a damage report for the plumbing only. Momentum then wanted to settle the claim for the plumbing and only after I had yet again told them about the cupboards and referenced the quotes sent they agreed to wait for the assessor. Fast forward to 18 July and the assessor finally came out and assessed the damage. Momentum then wanted to settle the claim for less than 60% of the lowest quote supp****. After another week of back and forth and finally they requested a detailed quote to send back to the assessors to review the amounts the contractor charges. It is now the 31st of July, more than a month later and I have been emailing a list of email recipients daily just requesting feedback with regards to the claim, just a simple we're working on it or it is not done yet. But nothing, just absolute dead silence. I am appalled by this level of service and I cannot wait to move my whole portfolio from them. The problem as I see it, is there is no one taking on the role of claims management. Every time you speak to another "consultant" and every email is answered by someone else. Claims get bounced up and down between consultants without anyone taking responsibility for the claim and client service. I will not recommend Momentum as a home and buildings insurer to anyone.
