Poor and Unfair Treatment by Momentum

I was involved in a collision with a client of Momentum on 12 March 2024. Their client was solely responsible for the said accident. I fully explained to Momentum how the accident occurred and also confirmed same via an accident report. I advised Momentum from the outset that the left side mirror of my vehicle was damaged as a result of the accident and that it is risky for me to drive my vehicle around without effecting repairs to the vehicle. On 4 April 2024, Momentum offered to pay me 80 percent of the damage to my vehicle. On 4 April 2024, I sent a detailed e-mail to Momentum, reiterating that there was no evasive action that could have been taken on my part to avoid the collision. I further requested the Momentum Liability Advisor, Wanda Ferreira to advise what evasive action I could have taken, based on the facts surrounding the collision that I had furnished her with. After sending the said mail, I called Wanda on 4 April 2024 and she merely stated verbally via a one liner that she was not prepared to amend the apportionment offer that she had made to me. I then requested her to furnish me with the contact details of her manager to enable me to escalate my complaint. I also requested a written response to the e-mail that I had sent to her, setting out my contestation of the said apportionment offer. She has to date not furnished me with any of the requested aforementioned. I am of the opinion that I have been treated very poorly and unfairly by Momentum as a third party. I require Momentum to amend the apportionment offer that they have made to me to a 100% offer in respect of the damage to my vehicle. If they stand by their apportionment offer, then as requested, they must advise what evasive action I could have taken to avoid the accident, based on the facts of the matter.
