Useless , Unexperienced ad employees and poor service delivery

Multi_choice has hired unexperienced and useless employees who doesn't even what they doing , there has been amount added in my account and no one can explain what the amount is for , all they tell me is the amount is an outstanding amount but they can't tell for witch month is that for, I actually wasted almost close to R400 of airtime calling over and over again getting same stupid people who doesn't know what they are doing , the supervisor onsite also explains to me there has been credit in my account which got me thinking when do multichoice credit its customers instead of debiting. Even the so called Finance department ( if ever it does exist ) none of the consultants could find their numbers nor direct my call. I am disappointed in this service and I have read several complains related to mine , this is stupid multichoice you need to up your game.
