Price Lock Department - Error in account

To Whom It May Concern, I have been calling DStv for the last two weeks as there is a problem with my account. They keep saying that the problem lies by the Price lock department as they were overcharging everybody as the system crashed. They keep saying that they can't put me through to the price lock department as they can't take calls. They will reescalation my problem. Please can someone call me as there shows an amount of R4066.62 that I owe. But you do take the monthly debit order. I will not be happy if that money gets taken of my account. Please let me know what details you need to fix this problem. Kind Regards Lizelle Swanepoel
