Don't order online, never any stock

I think my title says it all This is the 4th time this has happened to me, and I will most definitely not be ordering from Woolworths online again! What an utter waste of time and still having topay R50 delivery- what a cheek I ordered a few cooler bags, that were on sale from the food section (one beach cooler and 3 picnic coolers- added 4 bottles of water, then had a look at the sale items in clothing and found 3 items there to add to my basket. When reaching the checkout I was informed it will take longer to deliver my order as it comes from two different departments, I had no problem with this. Placed my order on the 8th, to receive it today, the 11th. This morning at 6:15 I missed a call from Woolworths (tried phoning back, no answer) but they left a voice message informing me that both the beach cooler and other cooler are out of stock. done. So now I wait for an order that has taken 3 days, and only half of the items I wanted. This is infuriating! This must be the worst online stock system there is! AT THE VERY LEAST PLACE A DISCLAIMER WHEN WE ORDER STATING THAT THE CHANCES ARE ****** GOOD YOU WONT HAVE STOCK ON ANYTHING ON PROMOTION AND WILL ONLY BE INFORMED OF THIS ON DELIVERY DAY. Go to your website now- that picnic cooler is STILL on sale. But you have no stock from 3 days ago? Come on!This is basically lying / false advertising, baiting customers in with reduced items, then only informing us you don't have it on the day of delivery, so we end up with the 4 items not on promo. Sneaky, very very sneaky.
