Cancelled insurance but it deducts.

<p>I have on November 2016 before the 10th cancelled a screen insurance on my Vodacom device because they did not give me more options on how I can insure my device so I felt ****** off. They deducted the insurance for that month, so I let it be as I thought i cancelled it later but then December it was deducted again and I can even see on my invoice that it will deduct again this month. I guess I'll have to reverse the whole debit order and put a stop on it, then pay subtract the insurance amount and hand in my payment because you guys want to rob me off. </p>
