Sending letters for settlement - never happened then sending another letter for settlement!

After 8 years,my tv license is still a mess.I got married sold my stuff go oversee with my husband who have a tv lisence for us.You still over charge me. Letters was faxed in 2009 with the proof and payment.Then you charge me for 8 years, I have paid more than 3000+ on the account. Your Kobus at NUDEBT send me a letter for settlement that was paid in December and now you still charge me R1995 and send me another settlement letter for R1500! SABC have so much ******* things happening, and trying making money, USING people who is trying to resolve the issue and you go and lie with letters sending to us and never KEEP TO THE AGREEMENT! WHY DO I NEED TO PAY! THIS IS MISLEADING INFORMATION THAT YOU ARE GIVEN TO US AN NOT KEEPING TO THE AGREEMENTS ON YOUR SIDE. WHO IS THIS KOBUS FROM NUDEBT! IS HE LEGAL OR ******* CAN HE BE SORTED OUT????
