Poor service for 3rf party claim

My car was hit by a momentum client in August while parked at work, she was kind enough to leave me a note with her details. From thereon her broker's kept in contact and informed me what was needed, in September a consultant of Momentum took over and sent me an email of what they needed. I sent back all required documents and it took him a month to get back to me again about the assessors. Netasses did the assessment and gave back feedback to Momentum to process claim, didn't hear anything for a week and when I contacted the consultant handling the 3rd party claim he tells me straight it might take more than 6 weeks to settle. How is it that I have to be inconvenienced and drive around with a huge dent on my door for 4 months and they think it's okay.
