Harassment by SABC!

Since 2018 i have been hounded by this company, even though i have followed all their regulations and requirements. In 2017 my partner and i bought a house together and therefore only needed one tv license. I sent SABC, their 2 different lawyers all the documents they requested to prove this but their administrators have not once acknowledged the receipt of these documents, even while i was still on the fone with them. I feel harassed and now just hang up when they call. Some idiot even ask me what happened to my tv when i told him I wasnt using it any longer! For real?!
