Delivery did not arrive & no refund details

I’ve placed two orders with Leroy Merlin this week. One order for two items, and then a single item. One of the first items is out of stock, yet no one can confirm when I will receive PoP and a refund for that product. The second order was cancelled without any notice. Also, insufficient details about proof of payment or refunds. The first item was to be delivered today - when the delivery truck arrived, my product was on the truck. No one has an explanation or can tell me where my product is.

This service is absolutely shocking.
