Device paid and still debited for it

Couple weeks back I contacted vodacom regarding my contract coming to and end <br> <br> I asked if I did not cancell would it continue to carry on as Normal apart from obviously being debited the device amount as at the end of a contract term the device effectively is paid up and you would only require paying for their services etc <br> <br> Marvin timm from vodacom responded saying that this was correct that I would no longer be debited the device amount which is 200 rand <br> <br> I have just been debited on my account the full amount of the contract including the device amount something Marvin timm assured me in writing that would not happen <br> <br> It's utterly disgraceful vodacom you have technically ****** money from my account which is not yours pay back the 200 rand and going forward ensure my debit is less the 200 rand the device is paid I will not tolerate this if it is not sorted I will file a complaint to consumer protection act , I will share my experience with social media and Wendy knowler on east coast radio consumer watch
