Leroy Merlin- I'm very disappointed

I ordered tiles, I was informed they'd be at the branch for collection in 3-5 days. I called after 3 days and was told we could collect. We went to collect but they weren't there. I waited until the following Mon 10 days later. Eventually they investigated and told me that the supplier was out of stock. They should have done due diligence immediately and followed up. My building was standing, the tiler waiting and nothing at all from Leroy Merlin.
