Contract downgrade to prepaid but contract still active

A totally useless SA company... I called in to downgrade my contract to prepaid. Had issues downgrading, Wrote a Hello Peter report. Vodacom did call and confirmed that my business contract was to be cancelled. At the beginning of September I received new minutes and data. This tends to lead me to believe that my contract has not been downgraded and Vodacom will send me another bill. OR Vodacom gave me free minutes and data = WHICH everyone knows will NEVER happen. I called Vodacom and the gentleman said he would escalate it and someone would call me soonest. I said the normal 24 to 48 weeks? If one is lucky. He giggled and said NO. Any way 24 to 48 hours is past and no call back from "escalations". I don't want a another bill !!!
