Unacceptable Customer Service

I've ordered a few food items from Woolworths online, never received my delivery. Yesterday they contacted at the very last minute to inform me that they won't be able to deliver my order due to the fact that it's not in their delivery region. What I find most fascinating is that they've delivered to my house twice before. Yet no refund or feedback was received since 8 April 2021. To me this type of customer service is unacceptable.
