Reliable Store order failure with no reason offered

The store was unable to fulfil my order placed on 24 June 2022. A refund was processed to my account for the order amount and it was received on 19 July 2022 after they were reported to the National Consumer Ombudsman. This after weekly trying to get updates on the order status such as a delivery date or tracking details from this store. The store should not accept orders if they cannot fulfil the order. At the very least, they must offer an estimated delivery date with an order status on their site. No reason for the failure to deliver was offered. The time wasted and now the effort I have to undertake to re-order from a different supplier at a higher cost is unacceptable in my opinion.
