Outsurance service for Third party claims is horrible...

On 5/8/17, I processed a 3rd party claim through to outsurance, I then only received feedback on 30/8/17, with a payout of 20k less than what I got a quote for, and a panel beater 50km away. I raised my concerns regarding the matter immediately and only 2/10/17 did the consultant respond with an alternative assessment closer to my area. As the third party person in this situation, i had to numerously call /email to find out if anything is happening. I took my vehicle to the panel beater allocated to ensure that the payout will be sufficient for the repair of my vehicle, and was informed that the bumper reinforcement cannot be fixed but needs to be repaired and cannot be bought second hand. In the assessment/quote the bumber reinformencement is allocated as a repair... I have raised the issue with the consultant and requested them to readjust the quote.... also sending proof of my bumper reinforcement being in pieces and beyond repair. I was then told that "I only have one quote for car damages?" I want the quote adjusted and this matter resolved... it been 3months!!!! If this is not resolved within the next 5 days I will be taking the matter further
