Too long to finalise a claim

it is now more than 2 weeks since my accident and this claim is still not finalised. I have provided my cell phone records, stamped bank statements (all of which I had to pay for) which I still do not see why it is necessary, I have provided consent to a range of tests and records to be obtained, you have brought me in for interrogation like I am a ******** and this is still going on. I have provided more than what was requested by your investigator. There is hardly any feedback given, Momentum does not want to put any of my requests in email, apparently all calls are recorded, so why do you not want to put the requests in writing? I have also requested an updated policy as I do not see why I should now pay for a car that you have written off, but was told I still need to pay for insurance, WHY?

please can this be finalised ASAP
