Vodacom Cancellation

I have been trying in vain to be assisted with a cancelation but none of your consultants are responding to me. I app**** for a contract online on the 30/11. When I received the delivery on the 05/12 I noticed it duplicated. In turn I called on the 07/12 to have it canceled and spoke to consultant by the name of Roslyn. She confirmed the cancelation has gone through. I have since called every second day, but your system was either offline or her emails was not working. If I did get to speak to a different consultant, they advised the cancelation was not put through. It is now going onto the 3rd month and I am sitting with this amount being debited off my account when I have not even opened the packaging. I am in a state of desperation to just have this picked up and my monies reversed on the account. I do not want to be held liable for this contract as this cost is not budgeted for. I sincerely beg for a response.
