We have to suffer for there errors

downgraded one of the packages from the extra to compact in june/july called them and advised on the new instalment to pay have been payment that amount since july, now they saying that i owe them R.00 - cause i have been short paying them, haven't received a statement from since may 2015. they disconnected me and until they have sorted it out i have to go without dstv which will take three days but because its weekend its gonna only be resolved by Tuesday, ( if it was short paid then why didn't contact me after a month of seeing that why wait 6 months before switching it off and not once did i receive a msg on my screen to say that i have an outstanding balance which i know they send if you even pay a day late. <br> i am very very upset as now i have to be inconvenienced and i have to waste my time and airtime calling them to see if its been sorted, and then the person i spoke this morning said she will call me back but i am still waiting for this call.
