Please train the staff well as I was so disappointed when I came in to buy Smart TV. My TV license is valid and I did show them the proof of payment but I couldn't use it because the cashier saw R265 balance. TV License people confirmed with me that everything is in order..and valid. I'm paying my TV license so I can use it. Please respect that.
