Handing me over after account was settled

I rented a car for 3 days. As i was driving down their driveway while returning it, I hit a very sharp curb at the back of their building which had no markings whatsoever. It was so sharp I even popped a tyre. I am sure I am not the first or last to hit it.<br> <br> The car was sent in for repairs and a lady from keys called me to tell me what the damages totalled. I told her I would pay her when I was back in town and to please email me an invoice. I never received the invoice but keys car hire kept trying to withdraw the money from my credit card without my permission. <br> <br> The next week when I was back in pretoria, I went into the branch to get my invoice and I settled the payment in full. <br> <br> Yesterday i received a phonecall from Bennett &amp
