Cancelled Telkom two months ago and still charged?

I cancelled my Telkom fixed line number *** in January and received a reply mail that they have received my cancellation but today received an account and I am still being charged for two months now. I tried phoning 10210 this morning waited 23 min for the call to be answered and was told by the lady that i should phone 10213 for cancellations. So I phoned 10213 and waited 31 mins and that consultant told me that I should phone 10210 for account queries.Tired of this nonsense that they just send you back and forth. I tried calling to resolve the problem so can someone please phone me to rectify this problem please ????
