Dismal Service Customer Service

In August I cancelled one of my lines. In spite of numerous calls and escalating the matter Vodacom still take money out of my bank account every month. Every time I call, I ask to speak to a manager. Vodacom refuse to have a manager speak to me. I have asked for Wayne's manager and Hypercia Mnisi, Mpho Phalane and Zakhele Dube to call me to resolve the matter. None called. I have asked for the relevant Vodacom Director's name and e-mail, but that is refused. One can not take a complaint any further than the consultant answering the call when one call Vodacom. I would like a sincere apology for the dismal service, a full refund and a ample donation to a charity of my choice.
