Online Purchase: Purchase not delivered

I placed an order and paid last week Thursday. The item showed a quantity of 11 available in stock for online orders. The next day my order was cancelled without any reason. After enquiring I was informed that the order was cancelled because of no stock being available and the order was referred to the Greenstore branch for fulfillment from their stock. However no feedback until now despite of several WhatsApp messages and emails from me.

It looks I lost my money. Leroy intends to keep it and hope that I will forget about it. Please immediately refund my purchase. I do not want the purcased items anymore. I have lost my trust in you.

Please contact me urgently to arrange for the refund.
