Woolworths online horrible service

Each time I order online I get told that they don’t have stock and they will just refund me ….. the people that call you don’t even care no have the curtesy to offer an alternative product …. You then have to wait 7-14 days for your refund ….. the worst customer service and poor management of the online website….. why does it allow you to order when they don’t have the products …. And it’s ALWAYS the case
