Incorrect Hotel Booking Dates - No Refund

In June 2013 I booked a flight to New Zealand via Singapore Airlines through Jannes Fouche at Flight Centre. On my return in mid July, I was supposed to be booked in at a hotel in Singapore. Jannes Fouche booked the incorrect dates (for June instead of July). As a result I was left stranded at Changi airport at night with no where to go. I traveled alone and it was extremely traumatic as it was my first ever international flight, In fact, it was only my third flight ever. I had to pay for my own airport transfer after I managed to secure a hotel. On my return I informed Jannes about my ordeal and he promised to look into it. In September 2013 he informed me that my airport transfer costs will be refunded and as compensation he would arrange a FIVE hundred rand discount on my next flight. What an insult. I was humiliated. In other words, I am expected to first spend more money at Flight Centre in order to get some sort of compensation. To add insult to injury, I STILL HAVE NOT RECEIVED MY AIRPORT TRANSFER REFUND!!!!!! Will I be using Flight Centre again? Retoric question I guess. I want my money and I want decent compensation for the trauma and horrible inconvenience that I suffered
