Waiting for refund

Tried to book a car with Woodford last week Thursday. Their telephone line rings until it goes to an automated voice mail that gives you an option to make a booking via whatsapp and i obliged. Waited and waited for someone to write back to me, until i reverted to booking online. I happily made and booking and paid in full. I arrived at Durban King Shaka Woodford office to be refused a car as i am not in possession of a credit card. I have been waiting for my refund ever since. I am not happy. Nondumiso Mnqandi ***
