Thrifty - doesn't care about their clients

I picked up my rental at OR Tambo shortly after 16:00 17/7/2019 I drove directly to my hotel in Morningside, Sandton and parked for the night. The next morning I drove to a few destinations all within short distance from each other. In the afternoon "my rental stopped shortly after reversing out of my parking. I called *** option 2 2x both the calls just dropped. Then 1 selected option 1 and asked to be put through to emergency, spoke to a man who said he would contact Sandton & get them to call me. Waited 20min, called *** option 1 begged for emergency help, she said she would speak to them & call me back. Waited +-20mins, called option 2 call dropped. Called again as I had no other number to call .... this went on, 10 calls over +- 1.5hrs! Each time that I managed to speak to someone I waited +-20mins for the promised call back before trying again. Eventually Sandton called & she said that she called me after the call from call centre but my phone was busy (very odd for a cellphone!) so I guess she didn't try again despite the fact that I was stuck and I had been calling a 24hr EMERGENCY number. She despatched a driver to me. I asked for him to call when he got to the centre so I could direct him but she said I should call him in 30mins to find out how far he was. I told her the battery on my phone was low and I couldn't keep calling. I guess the number she gave me was his private phone, Thrifty should have company phones for them to use when they are called out. My 1st call to Thrifty was about 14:20, I had a meeting at 15:00 which I couldn't make. The driver got to me close to 17:00, I had to drive to Sandton & exchange cars. I was stressed, panicking, thirsty and didn't leave the car because the window was 1/2 open. In hindsight after 1/2hr I should have just taken an Uber to my meeting and left Thrifty to find the car. This was disgusting service and I shall not use Thrifty again, I shall also tell many people of my experience." I logged a complaint of the text in "" on the Thrifty website for which I received an email apologising and that they will investigate. THEN I saw 2 amounts debited to my credit card, I got onto the chat on their website & received an invoice which wasn't very clear & the date/time of car exchange was 17hrs later than the actual exchange. The agent on the chat wasn't able to help so I emailed my query to which I didn't get any response. After calling the call centre I was given another email address to which I have also had no response. DO NOT USE THRIFTY CAR RENTALS!!!! They are fine until you hit a problem with them, they obviously have no client care ethic.
