Vodacom incompetence

I was contacted by a vodacom representative and offered a upgrade, by that time I was planning on cancelling my contract , which already expired and was running on month to month (as far as I know this happens when your contract runs its full term)The consultant advised me rather to downgrade and thereafter cancel as vodacoms service is bad (funny coming from a guy that eats and burps while talking to me) and it will take a few months. Unfortunately I followed his bad advise and agreed to it. A few days later I phoned in to get the cancellation process going, where I was informed that I am bound to another 24 month contact. I then did a upgrade reversal hoping and can get everything cancelled. A few days before my flight I contacted vodacom just to confirm everything is cancelled, the consultant confirmed that it was. A few days later I receive another debit order for my full amount. I contacted vodacom from Australia, costing me a few hundred rands, regarding this matter. I was informed that I requested a reversal of my reversal and that I phone in on the 28th requesting this, i then informed the consultant that I was on a airplane on that exact day and that would've been impossible. He then did another upgrade reversal and said I should phone back in 3 days. After 3 days I phoned back only to get told we need to do another reversal. Today I phoned only to be informed that my reversal was being processed but my term was still for another 2 years. The short story would be that commission hungry agents with very *********** staff will cause you extreme head ache. P.s my issue has still not been resolved and I will probably pay another month for a service I dont use.
