Appaling service from Momentum

I have never experienced such poor service before! I did not choose Momentum and ended up with them when they bought out Alexander Forbe's insurance clients. I have been trying to resolve a claim for a burst geyser since 13 January 2023, which is not yet resolved 2 months later!! I have emailed every email address I can find for Momentum, my client service consultant and now the claims agent and just can't seem to get the matter finalised or a suitable response. Company's need to have an email address or contact that will actually do something and follow up on complaints and not just disappear into the ethernet!!
