They just do not care at all

The worst service i have ever received . I booked a car to use in July for a holiday . I payed an amount to secure the booking for the car as it was a few months away . I called thrifty call center to cancel the booking as i no longer need the car . On the day when i called them they could not find my reservation on the system i was informed to call Randburg branch as that's where i will be getting the car . Called Randburg on the 19th to cancel was informed 5 to 10 working days for the refund to be done . I call them today and the agent i speak tells me that it was not done and i need to wait another 5 working days to get the refund . Informed him that i am not willing as i did my part its the company /Agent who failed the process why must wait longer for something that i requested done 3 weeks ago . he then informed me that he will get back to me with regards to the refund . I get an email which looks likes the refund request was only put has been now . i did not get a call back so i decided to call again . when I asked to be put through to the cancellations dept no one in that dept picks up or the the call is dropped . on the 7th time the reception lady gives me another number to call ********** /. When I dial that number i speak to the receptionist and she tried to put me through to the cancellation/refund dept after 10 minutes of holding i end up another dept which then has to try redirect me to the correct dept . i than ask to speak to a manager . i get through to a Mr Zubair I ask am i talking to the manager he responds " Some what" i inform him that i need to talk to a manager he says that i can talk to him . He informs me that since the request has been sent through i ill need to wait the 5 working days but since i use a certain bank account it could take 2 days . i have been trying to get this resolved today , the people who says that they will call me back do not call me back and now i am been told that i will have to wait a possible 5 working days when i as the customer did nothing wrong i followed the process it fails me and now I am the one who has to wait . What if that money was needed and I had plans for it ...Thrifty has failed me as a customer and honestly lost me as client but then i do not think they care about that cause who am I to them clearly no one as i have to wait 5 working days for a mistake they made
