Minus zero rating for service

Can I give a minus zero rating? I have been trying to cancel my TV licence for months now. I forwarded my cancellation email every two weeks. Guess what? I eventually got an email back yesterday requesting that I include a detail that was NEVER asked on the Cancellation Form. It only asks you the date from when you don't have a television set (you have to choose between broken, ******, donated). You also have to certify the form at SAPS. So, I had to complete a new form, wrote the detail the person requested above my signature as no provision is made or details requested other than the date. Had it certified again at SAPS. Well, let's see how long it is going to take them now to process my cancellation. I've read reviews on the internet of how people are battling to cancel theirs, it is shameful and nothing is being done about this. I saw again on the TV at our holiday apartment in November that there is just nothing on SABC/DSTV channels. An absolute waste of money. My grandson wanted to watch a children story... no luck there!!! Like Telkom, the Post Office and SAA, the SABC are an embarrassment to the new South Africa.
