HORRIBLE CUSTOMER SERVICE!!! Avoid them if you can

I rented out a car from Thrifty @ CPT Airport and returned it on 27 May 2019. No one told me that if I use a cheque card the refund will only be done between 7-14 working days because I would have then used my credit card instead. Shortly after I was billed for the petrol I used which is not a problem. However, that is not the issue here. The problem is that today is the 12th day and when I called the call center to inquire if I will get my refund in the coming 2 days I was told that Venice from CPT airport is the only one that can help me to see if my refund has been processed. I was given the following number ********** 121 and it doesn't work. I called the call center again and I was given the Branch manager's cell number. I spoke to him firstly at 08:58 and he took my name and number and said he would ask Venice to give me a call. At 11:15 I called again to follow up and he told me he is actually walking over to Venice and would ask her to call me shortly. At 12:05 I called again as I believe an hour is not "shortly" and now Craig is rejecting my calls and no longer taking my calls

All I want is my refund and nothing else. This was not my first time booking with Thrifty but it definitely is my last. I will also be advising our company to not allow any of our travel agents to book us on Thrifty. I WANT MY MONEY BACK
