Month to Month Contract Cancellation

I have been calling Telkom since September 21.09.2018 and asked them to cancel my month to month contract, but none of the agents I spoke have an idea whatsoever on how to cancel a month to month contract, Nokwanda Ngcobo (21.09.2018), Lethabo Magaga (28.09.2018), Tshepang Maamogoa (31.10.2018), spent more than 40 minutes on a phone and they all keep on saying we will ask our supervisor and send you email. I really don't know how the agents are trained at Telkom, because they are clueless. They can keep you on hold for more than 3 times. and still don't resolve your query. Please Telkom Cancel this contract, as I am fed-up.
