No refund

I had a replacement couch delivered on 05 Aug 2015. There was a credit of R1500.00 outstanding to me. I went to the Cresent store in DBN and requested a credit. a refund form was completed +- 15 Aug. My incorrect initials were used for the EFT and my credit does not reflect on my card. I was advised by Tatenda that the problem was with my bank and i need to contact them. Your company took the money off my card and now need to credit me. Not my problem if your banking institutions are not communicating. I am the customer you need to satisfy me and not advise me to do your work.
