Extremely poor and very frustrating service

A client of Discovery insured bumped my car on the 2nd of August 2018. I submitted my claim in the 2nd week after the accident because we waited for the party to send us the insurance details. In the interim I went to a reputable panelbeater for a quote. The panelbeater then said the damage on my car was R12 000 . Then Discovery insure sent us forms where in they wanted all the necessary documentation needed to proceed with the 3rd party claim. We received a email full and final settlement saying they were only paying less than 50% of my claim Which I then accepted, although I wasn't happy about it, but I just need to get my car fixed. In a nutshell up until today 20 November 2018, I have been back and forth with consultants telephonically, which have promised me with details about my claim . Unfortunately I have no records of my phone calls BUT I do have all the emails from the consultant, stating that my claim was approved and she was waiting for one signature to approve the payout. Please can you assist me urgently as it has been going on since early August until today, and I would really like to just fix my car.
