OMI does not care about 3rd Party clients

So on the 25th of May 2019, one of Omnisure’s clients drove into my vehicle while it was parked and she confirmed that she was focusing on her phone thus she drove into my vehicle. She admitted guilt, gave me her insurance details etc and I proceeded to phone omnisure and follow their company procedure for a claim against them. Damages to our vehicle amounted to plus minus R 46 000.00 and the costs for car hire in the process . Now keeping in mind this accident was no way my fault as the vehicle was stationery, she drove into me. Long story short omnisure offered a settlement of R32000.00 of a R46000.00 claim and there reasoning for this was that it was an agreement between the repairer and the assessors however the repairer disputed such and confirmed that the amount offer was not going to be enough to fix the vehicle. The assessors reviewed the quote after 2 weeks of fighting, sending emails and being ignored by Valencia Mokae. Subsequent to that I signed the release and they expect me to wait another 10 working days over and above the 4 months of being taken from pillar to post. Valencia is very rude and unprofessional, how she got this job is beyond me. I fail to understand as to why must we suffer for your insured's mistake at all. This is ridiculous. To-date I have not yet received my payment. Every time when I follow up with Valencia Mokae, she just ignore my emails. The fact that we am not paying premiums to OMI does not mean that we are not entitled to be treated fairly. You will never who might be your next customer.
