GETTING BILLED AFTER REQUESTING TO DISCONNECT

Hi, My Fiance has a dstv account and when I was on maternity leave we requested at the end of June 2015 to have our service disconnected. I spoke to Gomotso who was suppose to phone back but never did. When we reconnected we were charged 1807.00 before they would reconnect. How does dstv charge us for a whole month after we requested for it to be disconnected and did not pay. If we fail to pay we should be disconnected straight away. <br>
