Pathetic Service in 2020

Rented a car from Hertz Centurion on the ***, the staff there is unfriendly. When returning the car I had to wait for 30 minutes because the staff was out to collect the car from another customer, so no one to receive the car. Called customer relations for authorization cancellation , consultant tells me she is tired she can not help me, tried again the following week, Riaz Daniels this time tries to help, and said he had sent the email to FNB to cancellation, called FNB and this is what I get I spoke to Ayanda FNB Auth ref 405830,call ref RV***, she is saying you need to follow the correct procedure. Get Standard Bank to communicate with them. She is accusing you specific (Riyaaz Daniels) of repeating the same mistake now and again, and she does not understand why you are doing this to your customers. For me as your customer this is a very bad experience because I don’t even know the procedure, from day one I dealt with Hertz Car rental it was a horrifying experience, where one of your colleague told me she was tired and she was not going to help me, and yes she did not help me , you took over and this happens. I am not sure what to do anymore,
