Unauthorized deductions

I upgraded in May this year and I had a "cell band 3" insurance option from one of the vodacom subsidiaries on my account. I cancelled this whilst I was in the store doing the upgrade. I asked the consultant to make sure it is cancelled. He showed me the proof and I signed for this. On the June invoice I saw this "cell band 3" reappear.. I phoned once again and I was assured that there is no insurance policy active on my account. August suddenly I get two amounts debited from my account for insurance, then in September a single amount again. After numerous calls to vodacom and vodacom failing to phone me back, I eventually reached the insurance policy claims department where I spoke to Celeste. She told me that I had to reply to an sms with yes or no if I want my insurance to continue or to "automatically" activate it again. I NEVER HAD INSURANCE!! It was cancelled 2 months prior already. These deductions was made ********ly and constitutes theft in my view. How many other customers do vodacom give "automatic" insurance to whom doesnt, even realize it like I do? Its shocking that you now have to double check your vodacom invoice to make sure there is no unauthorized "automatic" packages suddenly added onto your account.
