One of the worst services received

I made a booking on the 22nd Jan for the 2nd of February in OR Tambo, I sent an email and WhatsApp to enquire but did not any assistance. I was reassured that the booking was made and that I’ll be receiving the car. Got to OR Tambo on the day and they wouldn’t release the car because I didn’t have my credit card(it was in Cape Town). An agent helped me in store to make a cancellation and Cc’d me on an email while I was there and called their head office and was told it would be sorted. I had to make new arrangements as I needed a car. I made other plans and was to expect my money the following week. It’s been the second week of me emailing, calling and sending WhatsApp and I keep being told they are working on it. This was one the worst services I’ve received. I need that money.
