Taking the Customer for a Ride

I purchased a fridge and TV on 21/12/2015. Game said delivery as arranged would take place 1/1/2016. My son waited all day for delivery - no show. I phoned them the next day and they were surprised that delivery was promised on the 1st. I was then informed that they did not have stock of the fridge and would have to wait until the 15th. No way! I told the salesperson I wanted my money back and what they have done is not in line with the consumer act. They phoned me back asking if I would accepted the floor model at a R200 discount. I consented. The however phoned me back a bit later and informed me that they sourced a brand new unit. All good. We arranged delivery for 1st thing Monday morning, it's now 17h00 and the salesman insist that the guys are in their way. My son has now set the whole of the 1st and the whole of the 4th of Jan waiting for a non existing delivery. I hereby request a refund and have Cc the Consumer Ombudsman on this issue
