Worst experience with woolies dash

Placed an order on woolies dash before 2pm today. I was informed by the shopper that the hot foods I ordered are out of stock. The order was only delivered just before 6pm this evening due to “technical issues” and “too many orders” I called the customer care line about 5 times and the same excuse was provided “the order will be delivered within 40 minutes” no apology. I was also informed that the fulfilment team would call me - that never happened. The level of disgust I am feeling is insane. I have only placed 2 orders with woolies dash and this will be the last one as I am deleting the app. I am so annoyed I could scream. I was told the out of stock items would be refunded within 7-14 days. If this does not happen I will be lodging a formal complaint with the consumer protector. NEVER AGAIN. WOOLIES I EXPECTED BETTER!!!
