Cancellation of old contract - Consumer Complaint for Vodacom - Head Office

good day. i cancelled my contract (after few calls) in march. they changed it to the R49 p.m contract. but i must still pay the old amount as well as the new amount. i phone numerous times with no luck. no one can help. they put me through to this one and that one and no one can help me. pleas, i just wanted to change to R49 p.m contract as the other contract expired january 2020. i keep paying and the account keeps staying in arrears. so i stopped payment last month until you can resolve the issue. the phone number: 0662396624
