Incomplete order delivered, missing item never delivered

I recently ordered some products from Woolworths, and DSV was their choice for a delivery company. The driver arrived within the agreed time slot. There was how ever an item missing, and on querying this with the driver, he acknowledged this, and even showed me his pick up form, where she showed me that there was not a tick to indicate that he had picked up the missing item. He then informed me that he would return to pick up the item and then come and deliver it. That was on Friday 3 July 2020 at 12:45. He has not returned and I have not received any update. I eventually managed to get to get through to Woolworths Customer Support to enquire about the missing item, and they have arranged to have it delivered today. When asking Woolworths if my order is marked as complete, they said yes it was, and that it gets marked as complete once the driver updates the delivery company's system which then updates the Woolworths system. I am taking the matter further with Woolworths because, I never received any form of communication to indicate that the order was delivered and completed, but as for DSV, I think it is wrong, and basically theft if a driver can mark an order as complete, meaning that all items have been delivered, when they have not been.
