Unauthorized debit order.

On the 30th July I called Miway to get a quote on insurance I basically signed up however I told the guy that I am not sure if I will get the car on the 02nd August so with regards to the commence date I was not sure ,he told me that if I do not get the car on that day I should just let them know I then told him that he should rather wait on my call to confirm as to when I will be fetching/getting the car and that they can debit my account for the \initiation fee".On the 31st of July 2015 I called MiWay to cancel the policy as I got a better rate at outsurance I spoke to some lady she confirmed that it was canceled I then also received a sms stating that it has been canceled.To my surprise today the 06th August my account was debited by Miway??? Is this normal business practice? Why was my account debited after the policy was canceled and also in the initial conversation I told the consultant I will call to say when they can debit the initiation fee?Can someone please help me understand what went wrong?i have called miway numerous times and keep getting sent from pillar to post without any assistance whatsoever <br> I need this problem sorted out today!!!!!!"""
