Refund

I returned a curtain which I bought and paid cash for on 30 April 2015 which costs R399.00. I have returned the curtain via post on 21 May 2015. I have called on 26 May 2015 and an agent confirmed that it was received by Home-choice. I have not received any indication as to when I receive my money back. The quality of the curtain was not what I was looking for and the colour was very bad. it looked different from the image on the catalogue.<br> <br> I have called numerous times and the agents just hung up on me. I also sent emails to their customer service and they are not responding. on the other hand their marketing department is harassing me with specials they have. I have received 5 calls yesterday only from sales agents, when I mention that I am awaiting a refund they just hung up on me.<br> <br> I bought the curtain online and I had to make the payment with in10 days for the order to be processed. why is that principle not used now that I must be refunded.
