Enforcing their products on clients

I took out a contract telephonically with telkom mobile and the consultant never informed me that if the contract expires it should be cancelled a month before.If he did i would never have taken the contract cause it doesn't make sense that a contract that is about to expire should be cancelled.Normally a cancellation goes hand in hand with cancellation fees and i find it so ridiculous.Now they keep deducting my money for as they call it value added services i've never requested.And to make matters worse i'm paying more now without a phone than what i did when i had the contract.Personally i see this as ***** cause i've never given them permission to take my money infact i don't want anything to do with them.They are the worse network ever cause i kept calling and the consultants now wanna force me to fill in a cancellation form for an expired contract.I want them to provide me with the tape where i agreed to them taking my money as they please and no one can help me with this.I'm not leaving this here i'll definitely take it further.I now get why their consultant Nicole tried to force me to take out a product i didn't want looks like company policy forcing clients.
