SABC TV LICENSE

Ever since I have informed SABC that I have sold my tv Dec 2018 they keep on sending me demands to pay and notices that I was handed over. I even gave the SABC the name and tv license nr of the person who bought it from me but they keep on harassing me. I got remarried after my wife passed away and relocated to the Cape. My wife doed have n tv and valid license which she pays every year. SABC DOESN'T WANT TO UNDERSTAND THIS AND I AM REALLY BEYOUND FED-UP WITH THEM.
