R47 000 paid for goods. No delivery. No refund.

Paid R47 000 for 4 iPads for business. 50% payment was made on Tuesday for the order to be placed and stock to be allocated. It was agreed that the devices would be delivered to the store by today (29 January 2016). Upon calling the store at 12h00, I was told the stock was not delivered and could not be sent through. The store manager had attempted to find the stock, but it will only be delivered on Tuesday. We placed the order because people are travelling for work and needed the items. No refund can be made immediately because eBucks was used as payment. No other arrangement can be made. I need the items that I have forked out money for. This is ridiculous. MassMart must make an arrangement for me to get this, even if from DionWired or Game, TODAY.
