Woolworths horrible online shopping

So on the 15 April 21 I bought some products online on my ww app, collection was scheduled for the 18th so as I ws ready to go collect my order, which I paid for I received a call, 3 days later that the products I bought are no longer available and will be refunded. Why today when the items were available online when I purchased, the lady told me she only received my order today (18th) and the product was finished my concern is why wait 3 dsts after my purchase to process my order? The lady was just not even concerned shame she blatantly told me they'll refund me. Now a refund will take atleast another 7 to 10 days and I needed those things if they were not available during my online purchase I 'd understand. I tried on several occasions to speak to we and I'm being sent from pillar to post, to the store in question and again to online support services. I'm very disappointed to what ww has dropped down to. Their online service denied me the convenience of an online service experience.
