No Service but STILL Being Billed

I have not had service since 20 JULY 2015. I am still being billed for service i have not had!!! I had paid all the outstanding amounts that were due. I had requested for my service to be put on hold which I was told later that they cannot do. I had asked for it to be cancelled which they are not doing!!! This was a MONTH TO MONTH contract. This is now the THIRD time I am writing on here!!! I want this solved NOW or i will follow with legal action!!! I have not had any follow ups to the responses with the references. TELKOM IS USELESS!!!
