Why is there no refund from DSTV/Multichoice

My television was ****** last week. The decoder was not taken. I phoned DSTV Customer Centre today and told them that I am unable to to make use of my subscription to DSTV as I have no TV . My payment date is 9 September so your consultant said that she would disconnect the service on 10 September. I do not want to pay for a service I am not using - I asked her to disconnect my DSTV TODAY and refund to my account the difference between 1 and 9 September - I expect a refund of at least a week's subscription but she said that as the decoder is still here, she can only disconnect on 10 September. This is nonsense - I repeat I have paid for a service I CANNOT access. Please arrange for the subscription to be disconnectedright away and credit my account. In fact I will probably not even bother to sign up with DSTV again, even when I do get another TV. I am actually quite tired of all of the religious movies you are flighting.
