Being billed for tgings I warned them about

On the 25th of January I called the muiltichoice call centre to downgrade my dstv package from premium to the cheapest package that u asked to schuedual on the 27th of January.<br> <br> On the 29th of January I noticed that I'm still viewing premium package and gave them a courtesy call to make them aware and to ensure I'm not billed for the extra days.<br> <br> It eventually switched over. Close to the middle of this month I noticed my dstv was off and gave them a call. They told me I have outstanding fees to pay. I explained the matter to the lady and she managed to reverse it and switch it back on.<br> <br> Closer to the 20th of February it went off again. Called them back, furiously and explained myself again and it got switched on again.<br> <br> I called them tonight to switch over to premium again only to hear that I have an outstanding amount again. The lady I spoke to seemed more upset than what I was for spending 10 mins explaining myself for the 4th time. She put me on hold and I ran out of airtime. <br> <br> Each time I phoned them I spent nothing less than 15mins on the phone which I think is unfair. As I am a customer and should be treated that way.
