Terrible service from a very rude consultant

So I am self employed, so my clients pay me when my job is done. So I don't have a salary date. So very often at the end of the month if I haven't gotten paid, I phone dstv and ask to please not disconnect my service, as I will pay a week or so later than normal. They make a note, change something on the system and my service goes on. So this month I did the same, yesterday I phone dstv asked them to extend it, they said no problem but this morning my service was disconnected. So I phoned again and spoke to Nandi. She then tells me it's absolutely impossible, my service cannot be connected unless I pay immediately. So I told her the consultants have done this for me multiple times before. And she basically calls me a ****! And says no they didn't, because it cannot be done. So I ask to speak to a manager, and she puts me on hold and just leaves me there. This is definitely the worst service I ever got from dstv from the rudest consultant!
