Refund taking too long

I purchased items online from Makro and paid online via Credit Card. I was later contacted via phone call to inform me that the supplier could not fulfill the order and would be refunded my money into the credit card. A few days later I received an email that the money had been refunded. However it is yet to appear in my account. I have contacted Makro twice and have been advised to wait 14 days for the funds to appear. This is seriously unfair. I would understand if the payment had been EFT or the like but as for Credit Card refunds back into the account are much simpler as I have experienced with other businesses.

Makro is willing to accept instant payment but makes clients with 14 days while incurring interest costs and waiting to purchase the item no longer available from another retailer. The loss is not just in the amount to be refunded but in the interest costs incurred and opportunity time to purchase from another retailer. If this is a gift the target event may long have passed before the refund has landed.

I am appealing to Makro to be as efficient in refunds as they are with sales especially in the cases where Makro cancels because they cannot fulfill the order.
