Poor service at its peak

I had an enquiry regarding my TV licence as I have moved back home and for a year now have not used the set as am no longer employed. I settled all my areas and wanted to know any procedure I can take to make sure I am not billed further. Firstly one consultant answered and transferred me. I then stayed on hold for over seven minutes. When the next consultant answered I asked why it took so long for them to pick up, without apologising for that she rudely said "we are busy, how can I assist you?" I asked what I needed to but the conversation was not easy flowing because I was receiving bad attitude. Then she just put me on hold while I was speaking, came back and told me to send them an affidavit, I asked what happens next after I send the affidavit, she was so rude and said just send the affidavit. I was so angry at this point and instead she repeated only the information she gave before instead of answering my question. I reminded her that the purpose of my call is to get the procedure from beginning to end. Meaning I want to know if I will still be billed of not and she just said "just send the affidavit" and hung up on me. Needles to say we call using our own airtime. The first thing that I would expect is courtesy. I am not sure if in their training these people are taught that a customer can sense your smile or lack of it from the other side and for her to go an extra mile of rudeness even to cut a call she didn't make. Sabc TV licence's service is so disappointing
