Poor service from Dstv(MultiChoice)

I had a Showmax subscription for a number of years to which at some stage DSTV offered me a streaming subscription with my Showmax to which I’ve had for a bit of time. It was recently brought to my attention that the subscription ended to which I now have to pay R609 and all this with prior notification that my subscription would be ending. I was told I would be contacted on the 22nd of Sept. I believe I was contacted at 9:39am but was unable to take the call as I was in a meeting at the same time. Usually it been seen that the individual who tried to call would do so more than once but not in Dstv(MultiChoice’s) case. I would like to cancel my Dstv subscription but the mydstv portal does not allow me to do this. I take this has poor service & lack of communication from Dstv(Multichoice).
