BAB BAD Rotten Vodacom Service

From April i have been struggling with them, firstly the expired contract was not to be upgraded. i now sit with a very different billable amount each moth and each time i call them (19 consultants ) they still dont get the fact that i DOP NOT WANT that contract. on the 22 of October i was told by one of the supervisors that everything will be reversed and by 1 November the number will be disconnected.. Nothing happened
