Unnecessary Harassment

Received a call stating that my account with Multichoice is in arrears (the amount was very odd) but when I asked the agent questions, she couldn't provide proper answers because I know I have not been using Multichoice for over two years as I stream on Netflix and Showmax. I then told the agent that I am not gonna pay for monies I have no knowledge of I then called Multichoice and they confirmed that I do not owe anything and that my account is R0.00, not in arrears. So there's definitely a lack of communications between the two of them. Thus causing unnecessary stress and confusion, imagine if I had agreed to pay?! Tjo.
