Dishonest false asvertising

I paid R1000 ticket to see Robert Kiyosaki at the recent NAC South Africa event. We only got to see Robert for 30 minutes on day 1 and another 30 minutes on day 2. The rest of the time we had other speakers trying to sell us there programs. From 9am to 7pm sitting through sales pitch after sales pitch. It was grueling. I sent an email asking for a refund as they event was nothing like it was advertised and they still have not gotten back to me date. Very dishonest
