Overcharge error and call center agent unable to help in anyway.

Today was my due day to pay my dstv account, I made a payment at 6am this morning, and yet my account is suspended & requesting I pay an additional R50 to open my account(as is my payment was late) . A call center agent tells me, she agrees that there's an error but is unable to anything about it and I should call back at 13h00 when her manager gets in. That is the most ridiculous thing I've heard. Horrible service from dstv and I am very unhappy.
