Incompotent delivery service

I placed a small order on their website to be delivered to my home

They called me to see that someone would be home the next day. That day I received a notification that the delivery had been completed, yet I had received noithing

When I contacted them it turns out it was returned to the warehouse for an undisclosed reason. They indicated they would schedule another delivery

After hearing nothing for a few days I called them again, and they said they would schedule a delivery.

Someone phoned me a couple of days later to ask whether I just wanted to cancel the order but I declined as I need the product.

I phoned again on the 9th of March to see if it was every going to be delivered and I was told that it had been delivered.

This is a completely useless service if they are unable to communicate and actually deliver a product. As it stands I am now awaiting some response as to where this was actually delivered to and how this issue will be rectified

I don't expect to be using Leroy Merlin going forward
