STILL BEING CHARGED FOR A CANCELLATION.

I have been trying to cancel a service since March through Alisom Communications. In August I got notification that it is finally cancelled, yet my December account still have the R7000.00 charge on it. I have cut costs everywhere else to keep all our staff in positions and yet Vodacom can still charge me for a service not used. Not one person I dealt with actually cares about the situation. I am sure they earn the salaries every month.
