Please stay away from Coricraft Cresta

Middle December I bought two leather couches from Coricraft Cresta. On the day of delivery I was phoned and told that there was a mistake and the couches are out of stock. I am convinced it was given to somebody else. I was then told that the couches needs to be manufactured and that I will only receive it in March 2016. I then told them that I would buy elsewhere, but I would take a bedroom set and then can refund me the balance of about R8400. That deal was done on 21 December 2015. In January I started phoning the store, eventually I was told they would give me the bedroom suite on the floor, which I wasn't really happy with but as it has taken so long I decided to do it. Today 22 January it was supposed to be delivered only to be phoned by Mark and told that the warehouse was supposed to send a replacement set and that they cannot deliver. It is now more than a month and I have no furniture or refund. I was also told that they can only process the refund after the bedroom suite has been delivered, which now has proven to be not true. I am out of ideas how to deal with this. Please stay away from this store.
