Poor account handling and poor customer service

On the 2 May 2017 I called to cancel my Premium subscription. Because I'm a panelist I was to contact someone else to cancel this. Ref: ********** /i12 I have since left the country and 6 months later they are still taking money off my account. How do companies get away with ******* like this. That's R5244 that was taken from me. I called again today ********** 000 and was told I'm a panelist and ,ust call ********** 289. That guy says he is commercial only and I must call ********** 222 and they must deal with my cancellation. Called again and given the ********** 121 number which I can't call from overseas. What do I do now? How do I cancel and get back my money which was taken from me. Why is this so difficult!
