Cancelled contract still being charged

I cancelled one of my two internet contracts at the end of July this year when the contract came to an end, for which I have a reference number. I paid in a final amount and the consultant told me it had been finalised and no further payments would be deducted. I noticed this month that Telkom is still deducting money for this internet account. I went back through my statements and have been charged for Aug, Sept, Oct and Nov. <br> <br> After being bounced around to serval consultants on the customer support line, I went into the shop two weeks ago. The consultant informed the had lodged a request for this to be sorted and gave me a case number. He noted Telkom would contact me with 3 days. Its now two weeks later, no correspondence from Telkom and as month end looms I expect I will be charged again. <br> <br> I am high annoyed with this and cannot believe the poor service I have received. At this point I suppose I'll just cancel my other contract??? I can serious advise no one uses their *********** services!
