Poor Service Ever

I sent an email below to Vodacom to cancel and was contacted by someone who couldn't advise why was I subscribed and to what product also who subscribed me. He said they have reversed the R100+ not sure to which account the we conveniently got cutoff. The consultant did not call me immediately, he called me back after about 10 minutes while I was on the line with a customer and never tried again. I cannot be overcharged because I subscribed to something that hasn't got the name. I will reverse the debit orders from this month if they don't cancel the contract.

Kindly be advised that I would like to cancel the phone contract that I have with Vodacom due to incorrect billing that I complained about it and No service that I experienced. I logged complaints on HelloPeter hoping I will get some attention, I was contacted once while I was driving after work and the guy promised to get back to me the next day and as usual never received any call from Vodacom. I requested for the process on how to cancel the contract still waiting. I had phone and tablets contracts with Vodacom for the past years and never had problems at all. I would like to cancel the contract with immediate effect and please advise what else I need to do. Should you ignore my request, I will reverse the next debit orders. Should I not get feedback by next week, I will post this on social media.
