Complaint @Tempest car hire. OR Tambo international Airport

I booked a car on the 26th via booking.com with tempest car hire at the OR Tambo international Airport. The sum of R2074.72 was deducted from my debit mastercard. Today upon arrival I found Mandla and I was requested to produce a credit card which I was never told about. When I asked them to cancel and refund me he told me that there's nothing he can do for me .

He gave me numbers from the UK***ners) to call and told me that they are just agents. These are the numbers: ***5521 and ***366. They also told me to reply to the "noreply" email by booking.com, which is not gonna help.

I would like to have my booking canceled and receive my money back as soon as possible.

Thank you.
