Cross border not granted while all documents were sent 2 days before picking up the car

Hi

I booked and paid for a rented car with Hertz on the 10-10-2022 to be picked up on the 13-10-2022. I sent all required documents to the cross border email and the other reception email on Tuesday the 11-10-2022 since I was going to cross the border with the car and there was no acknowledgement of the email nor any response. On Thursday the 13-10-2022 I picked up the car at OR Tambo airport around 09:25 am then paid the deposit after that the lady by the name of Didi was not even aware that I'm crossing the border with the car while I sent all documents 2 days ago. She asked for my license and I gave her my temporary A4 license since my driver's license expired and I also gave her the expired card. She gave me the car keys then after asked me to pick up the car seat at their offices. I received a call from Didi before 12 luckily I was still in the airport and she told me her manager said I won't be allowed to cross the border since I don't have e-Natis papers that they did not issue due to my temporary license I said this is the same license I sent twice two days ago and you did not respond. We sat at the airport for more than 3 hours waiting for those papers and a lady by the name of Martheron I'm not sure about the spelling but she said she will send all my documents to risk and ask them to approve and release the papers. Eventually we received the papers 3 hours later, while I'm also travelling with a toddler. I will never ever use Hertz again they are not professional.
