DISAPPOINTED

Am so disappointed with Multichoice. Last month payment was made on the 20 June to my surprise my service is disconnected to that on the 17 July. I just want to know what is there service period is month to month or what? Now I will have to pay again connection fee again when I made payment. I now my payment day is on the 15 of every month but the past 5 months I have being making payment on the 20. They never try to accommodate me I have being paying the connection fees and they never try to give me my 5 day grace period for those days. ***
