Bait marketing

I ordered a Samsung cellphone on the 26 April 2015 and paid the full Amount and I was promised that it will be delivered within two days after payment is received, two days came and pass and still no cellphone delivered then I contacted them through twitter and they said they will look into it. On Monday 4th of may, my order was cancelled saying they don't have stock and they won't be getting more stock of that specific cellphone then on Tuesday 5th of may I notice that they are advertising the same cellphone (special import) that they said they don't have the stock and they won't be getting more but this time they advertising it at a higher price meaning the 1st adverti*****t was a bait marketing which the consumer protection Act is against. And now they are taking their time to refund my money, they told me my money will appear as Credit on my profile within 24 hours, it have been more than 48 hours and still no credit on my profile, they are still sitting on my money. This was clearly a bait advertiment to get me to buy something else with my credit, anyone know how to lodge a complaint with the protection Act? Serious Action should be taking against [URL Removed]
