No stock and no refund

I bought 3 items from Coricraft on 12 Dec 2015. Paid cash for the invoice which amounted to just over R11000.00 My delivery was promised to me by 14 March 2016. I patiently waited for this when they contaced to to say my delivery will reach me by Friday 26 Feb. I asked to move it to Saturday 27 Feb 2016. Then the waiting started. I waited after received 2 different smsses with 2 different sets of delivery times. I finally called them and found my delivery. This was eventually delivered at 13:50. Then on delivery I am told that only 2 of the three items were in stock. I was furious because I paid and secured stock already on the 12th of December. I went to the store the very next sunday morning to ask for a refund. They did try to sell me the item of the floor and I said no thanks, it is now over a week and I have not heard from them or my refund. I call but no one is available or get back to me if I leave a message. Very upset with this 'upperclass' store. They are getting interest on my money and it is around R3295.00. Quick to take your money, but terrible service from them. I would rather support another store in future.
