Pathetic service from Woollies online

Absolute pathetic processes and service from Woolworths online. I placed an order via Woollies Online on 24 January 2018, for delivery on 2 February 2018 as we were relocating and moving into our new home on 2 Feb. My order included 20 5Ls of bottles water. Today, 2 February 2018, I was contacted just after 12pm, thus LESS THAN TWO HOURS PRIOR TO THE SCHEDULED DELIVERY TIME, to be told the 5Ls are out of stock. When I ordered and you IMMEDIATELY TOOK MY MONEY IT WAS NOT OUT OF STOCK. My brother-in-law ordered 5Ls AFTER ME, YET THEY RECEIVED THEIR DELIVERY. Your processes obviously suck. How can you base stock on whose delivery date is first instead of who ordered? I repeat again, WHEN I PLACED MY ORDER ON THE 24TH OF JANUARY IT WAS NOT OUT OF STOCK. So thank you Woollies for messing up my first day and moving in day into our new home in Cape Town. I wish I never ordered from Woollies. This is such an easy decision now to close my account. Let me guess, I will now also have to wait forever for my refund.
