Waiting for my refund for almost 3 weeks

I wanted to purchase a queen size bed at Morkels Tzaneen. Betty the sales lady informed me that there was stock. I did a EFT from Absa Account to FNB Account. Wednesday, 13 January 2016. To confirm that the money is in the account and that I can come and collect my bed because I needed that bed urgently. Betty was not in the office then they transferred me to Lucas the Manager. He informed me that they do not have stock and I can receive the bed in a week. I told that this will not work for me, I need my refund. It Is been almost 3 weeks and I do not have my money back. I phone them almost everyday and all they say is there is a system error and they cannot give me an ETA date on when I will be able to receive my refund.<br> <br> Please can you help me.
