Contract cancelled but still been charged

I went into Westwood Mall Telkom Mobile and had my contract cancelled in the beginning of January 2016, i was assured by the consultant that no other payments will go of my account and paid the other amount to have the contract cancelled at the end of January 2016. I now look at my bank statement and there is a payment taken by Telkom mobile, yet i discarded the sim card and had the contract cancelled in January and have not used it since, but am paying for it! This is ridiculous service when consultants can not do there jobs properly! I expect my money back and no further payments to be taken! i am still awaiting a response from someone from Telkom!<br> <br> Ridiculous service.
