Woodford the worst

Zero..I rate Woodford Zero. On 29 September I booked and paid in full for a car rental. I collected the vehicle on 30 September, showed my proof payment to the clerk at the Loop Street branch in Cape Town. He then proceeded to charge me a further R28 586.70. When I received the confirmation statement a few hours later I immediately phoned the branched. They acknowledged the mistake and promised to refund the difference after deducting an R8000 deposit. it is now 25 days later, despite numerous emails, personal visits to the branch and phone calls, I am yet to receive my refund. I'm told to wait. This is by far the worst car rental service I've ever had to deal with. I've had communications with Natalie, Shadley, Tafadzwa Kambewa and nameless people, who do not put their names down to the emails, all making empty promises. I have asked for proof of the refund...nothing.... An absolute disgrace.
