Woodford still haven’t refunded me for money wrongfully billed ro my account

Woodford does not refund money wrongfully billed to my account. I reported to you that you have billed me incorrectly for 8300km where I only drove about 1300km. Despite my emails and confirmation that you have corrected this and where I was supposed to give me a refund on my R4000 deposit, you billed me R49747 on my credit card. I have given you a very bad review on Hello Peter. I will rectify this after a personal apology from the MD and a refund of R49747, plus my refund on my R4000 deposit minus the petrol top up, This was a new car and only had about 1700km on when I returned the car.
