Refund not paid

I purchased a headboard at Bellville Furniture Somerset branch on the 13th of August and paid R2598.00 in full, i was informed that the headboard will be ready in 3 weeks time and i was fine with that, time went by 3 weeks passed and after 6 weeks i called in to find out what was going on, they said they will get back to me. i waited no one called me about anything. A week after that i received a call from one of the ladies there at the store and said my headboard is ready they will deliver it i said its fine , she then called again and the delivery is outside . i called my Mom at home to open the gate for them and my Mom confirmed there was no one at the gate. I got so angry and felt so disrespected as a customer that has paid in full and waited too long for something i paid for. I called them in again and told them to give me my refund . I sent the banking details, I spoke to the Manager Griffith several times he is been promising that my refund will be paid into my account, he is currently ignoring my calls . I am still waiting for my refund until this day. i sent the email as well no one has responded back to me. I now need to know what Am I suppose to do in this case? I have been fooled by Bellville Furniture employees for a very long time. it is now the 4th month.
