Does it have an effect on my credit score?

Hi, I have a problem with the TV licence, I have never purchased any TV. I started getting messages that I'm owing " them" for having a TV licence, I have never purchased any TV. The also sent me sms's that they will give me over. Here is one message from them: "MS S FICK, Your OVERDUE TV Lic Bal is R954.00. PAY SETTLEMENT OF R530.00 TODAY. Visit www.tvlic.co.za or Call: ***"
