Fab Furniture ignores my refund requests

I had purchased a coffee table from the Clearwater branch. Which then became unavailable after paying it in full in January 2016, because they say their supplier had discontinued that type. I then requested for a refund because I did not like the other they had. I was advised to send an email to request this refund to [Email Removed] and [Email Removed] I received no response. In February I contacted head office, and I was told to contact ***. I spoke to Zama, whom assisted me, she said that she had captured the refund request to her boss, whom does refunds every Friday. Since February I have been waiting, no refund has been made, I call almost every week since feb and get nowhere. On the 12th April, she contacted me to say that she has done everything on her side, her boss is not responding to any of her communication regarding this refund, even after telling him that I have been requesting it since Jan. So I don't how else to deal with this, as there is no one to assist me further, or to escalate to. The total refund is of R1800, I have sent my original invoice and proof of all payments, as well as my banking details.
