Still not sorted, even after they called me back!!!

In April I wrote a review regarding Vodacom lies and disfunctionality! Vodacom called me within days, very polite and friendly and told me that they will finally sort out my complaint. A few days later they said they have stopped the "*******" contract and changed it to a prepaid, and they will see if they can refund me for all the months. It is now 8 July and still the debit order goes off every month. As I have stated before, there seems to be a problem in the communication between different departments in Vodacom. I was so happy when they called and told me it is now sorted after more than a year. But the department that called me seems to not have spoken to the department that should have canceled it. Disfunctionality!!!
