Telkom service NIGHTMARE !

I submitted my cancellation online more than a month ago . So this morning I tried to contact them.... I waited exactly 20 minutes for them to answer.. just for the lady to ask me how I cancelled... I then told her I went into the Greenstone Telkom store and the lady there said they cant help me and that I need to do it online. They gave me an A4 printed paper with a step by step instruction on how to cancel.... So I old her I followed the instructions on the paper .... She then told me no thats wrong I didn't complete the cancellation and then just put the phone down while I was talking. This is the worst service I ever received and waisted 20 minutes of my life. This is unacceptable I will be cancelling everything I have with Telkom !
