poor service

I returned the rental car on the 16/11/2015 and i was promised that i will get my refund after four working days. I then approached George on sunday 22/11/15 to ask him what might cause the delay for my payment. He then said he will speak to his manager the following day about the issue. The following day at around 12h00, I then phoned vanderbijlpark branch only to find out that no follow up has been made. After 14h00 i went to the branch(vnderbijl) to make a follow up, I then spoke to Joshua(manager) who made a call to head office so that i can speak to them personally. I spoke to Tyler who told me that they didnt have my account number but the statement they sent to me read that it was paid on 18/11/2015 to my visa mastercard. he then retrieved my account number on the system saying vanderbijl park branch didnt upload my details. he further told me that i can only get my money after two days after processing the transaction. Im not happy cause i wanted to use that money over the weekend and i waisted my money travelling to vanderbijl on two occassions and im still going to wait for this money which is not my fault that they couldnt pay it on time. I also sent an e-mail yesterday.
