Refund on out of stock order

On 1 September 2017 I placed an order for a Seattle Double Bed and Cross Leg Wooden Pedestal. The order went through and said awaiting payment. On 2 September I did an EFT transfer for the order. On 3 September I received a mail saying that they are out of stock on both items, that my order has been cancelled and I have been issued with a MRP voucher for R3800. I phoned customer care and explained that I do not want the voucher as this is a large amount spent and I only spent it because I needed a bed urgently and asked to be refunded onto my credit card or in cash. They then proceeded to tell me that all refunds into a bank account or credit card will take 14 working days to clear - which is disgusting. Happy to take your money but very slow to return it when they are at fault. Then I asked if I could be refunded in cash and was told that it might take a while to refund this amount as most stores do not have cash and the manager from Retail Crossing will contact me today when I can come get the cash. I am still waiting. And in the meantime waiting for this refund of MY cash, I have to sleep on the floor with my pregnant belly as I do not have another R4000 lying around in my accounts for me to go buy another bed!!!
