Issues with DSTV premium streaming cancellations

I am facing big issues with DSTv cancellations. I had a DSTV premium streaming account which I tried to cancel on 14th March and enable DSTV Premium package. The operator gave instructions and I followed it and it did not allow me to cancel. The operator came back later to just provide me with the prorata amount that I need to pay for DSTV premium package only . This month I receive my bill and came to know that my premium package is still not cancelled. When I contacted live chat, I am not given an assurance 1. I am unable to cancel the streaming package from my end , When will DSTv resolve this issue 2. What is the correct amount I awe DSTv 3. If my package will not be disconnected while we wait for everything to be resolved
