Verbally abused and threatened.

I booked airport parking at OR Tambo airport through Looking4.com with AIPS and on my return flight, the instructions received were to call the parking attendants once landed. My car was eventually delivered to me 45 minutes later. When arranging payment I was not happy with the payment option and requested a tax Invoice with banking details so that my company could do an EFT. The driver and the manager who was nearby proceeded to snatch my keys from my car and demanded I pay via e-wallet. After quite a disagreement, I was threatened that my tyres would be slashed, called all sorts of names and told in future to rather book with a "white" company. This is totally unacceptable and utterly disgusting behavior. I will never use looking4.com again if AIPS continues to be an option.
