Hi so sabc keeps sending me sms's saying that I am owning them outstanding tv license . I have never purchased a tv license in my life. They told me that it was bought in Pretoria but I live in durban I told them its ***** they then asked for a police affidavit to be emailed to them which I did do but now they keep sending me sms's saying failure to pay will result in bad name etc
