Incompetence!

I called the call-center 4 times to mention that I have moved from PE to Durban and now live with my dad. So I have given him my TV set. My TV license should therefore be cancelled. The gentleman on the other side of the line said that I need to get an affidavit and email to them, which I did the next day. After a week of still receiving SMS; to pay the license, I called again only to be told that there was some outstanding info on the affidavit (thanks for calling me and advising!!) - I then got another affidavit completed. Still no feedback again after a week. I called in now only to be told that it was incorrect info that I was given, they cannot cancel the TV license, i am liable for it! extremely frustrating service and incorrect info given that really has inconvenienced me! Please can a manager contact me urgently to rectify.
