Woolies Dash Disappointment

I have used Woolies Dash Delivery since 2021 and for the most part have been very pleased with their service. Lately I received an order with a couple of items missing as they were out of stock. As usual, the app takes the original sale amount out of your card. Instead of refunding the amount owed from the items not delivered, Woolworths took the amended amount out the account as well and the original amount is still on hold in my card. My bank won't release it back into my account without instruction from Woolworths and yet all my attempts to contact Woolworths to resolve the issue has been ignored for almost 3 weeks now. Contacting the call centre is a waste of time as the automated options will not allow you to talk to anyone unless it is a Woolworths account related query. Competitor services either refund the amount or credit it to future purchases. Be aware of the risks when items are out of stock but still available on the site.
