Wrong subscription

To date my subscription, has not been fixed. I’m on a 24 month subscription. Which is R 559, all of a sudden, I’m being billed 674. I have made numerous of calls, DStv consults clearly don’t understand their own systems. I was told that a senior consultant will call me.. this is not rocket science.do the math I want my subscription to be put back on 559… this is day light ******* Hire consultant that is competent I want a manager to call? Or I will logde a formal complaint with the consumer right
