Terrible support after incorrect item was delivered

I ordered 3 different products online and 1 of the items delivered was incorrect. After contacting Leroy Merlin everyday for almost a week to arrange the delivery of the item I actually ordered, they told me that first they'll collect the wrongly delivered item and then after that deliver the correct one.

It seems that when Leroy Merlin makes a mistake with an order that the customer will be the one that needs to continuously follow up with them to sort it out and then also wait until they one day decide that they'll bring you what you should have gotten weeks before and already paid for.
