Very bad customer service from Nina Zembe

I’m not happy with the customer service from Nina Zembe especially the arrangements around the courtesy vehicle. We are not allowed to communicate with the car rental company but only through Santam. She just booked the vehicle for two weeks before the two weeks expired, I contact the panel beaters to ask them more or less they think the vehicle will be ready for collection, that was during the last week of November because the last extension of the courtesy vehicle was until 2 December 2024. When I spoke to the panel beaters company they suggest to play safe ask for extension until 6 December which I did. Nina came back with a screenshot from the panel beaters the extension is granted until 4 December 2024. Just after I received the e mail from Nina the panel beater sent me an e mail and message to inform e the delivery of my vehicle will be on 6 December 2024. I had to send Nina again an e mail to request extension again until 6 December 2024 which she eventually did. On 2 December 2024 the car rental company called me to remind me that the car is only booked until 2 December 2024, but I asked Nina on 26 or 27 November 2024 to extend the courtesy vehicle until 6 December 2024 which she never did. I informed the car rental company and I was actually shocked that the extension has not been done as yet. I sent Nina again an e mail to ask her to extend the courtesy vehicle and informed her the car rental called me on 2 December because they wanted to collect the vehicle from me. On 5 December I sent Nina an e mail the early evening to inform her that the courtesy vehicle is dropped off at the panel beaters and that the company will be available until 10 the morning on 6 December 2024 due to their year end function. The car rental company called me this morning on 9 December 2024 to collect the car which was due for collection on 6 December 2024 already. Nina never informed the car rental company about the fact that the courtesy vehicle is ready for collection.
