No regard for customer service

Early in June, my neighbor had mistakenly bumped my vehicle, he let me know and said I could claim from his 3rd party insurance, he is with Budget. After he did the necessities, I then called Budget to register, on the 14th of June, since then, I did not hear from anyone, till I called on the 24th of June to follow up, I was told I should have received something from Kagiso Sethsogoe, which I has not and Netshedzo Nematshema who I spoke to at the time assisted by sending me the email. I then sent all the required docs through to TIH, on the 28th of June. After sending my documents through, I get no response from anyone, unless I follow up. On Monday 4 July, I call to follow up, Kagiso advised his mail was down and sent me the offer letter. I took my vehicle to renew-it in Rivonia for a quote and the bumper needs to be replaced as it is cracked, the complete repair quote to fix the damage is R20 130.97, I received an offer letter from Kagiso, with an amount of R9374.74, this is less than half of what it costs to repair the vehicle and further to this, how does a virtual assessment done by your assessor supersede a physical inspection. I immediately told Kagiso on the phone that I cannot except this offer and I rep**** to his mail as well, this was on Monday, 4 July. To date, I have made numerous calls and sent multiple emails to Kagiso, and clearly he thinks nothing of customer service, since Monday, he has not responded to any of my mails or returned any of my calls. On Tuesday, 5 July, I attempted calling, he assured me I would get feedback by COB, still have not heard from him. This is totally unacceptable, I have reported TIH to the insurance ombudsman as I am getting no where with your *********** staff who lack common courtesy for customers. I am traveling in the next 2 weeks and need my vehicle fixed, I was told it takes 5 days for the assessor to come back on a dispute, but how will I get my vehicle fixed before I travel?
