Shocking ****** vehicle claim approval

Momentum Insure were very good at signing me on as a client rather quickly. My car was ****** in September and all documentation was submitted and closed out on the 27th of October. Each Claim Advisor I have spoken to has subsequently gone on leave. I have spoken to 5 to date. Nobody comes back to me with an update/feedback or resolution. I have been holding the line as I write this review for 24 minutes. Managers also seem to never be available and messages are taken and nothing moves forward. It is a fairly simple claim. Please do yourselves a favour and stick with your more expensive Insurers. At least you receive feedback
