Selling broken products, and they aren't bringing a replacement

I bought 4 industrial sliding doors from Leroy Merlin on 12 October 2024. They delivered the doors 3 days later. 1 of the doors was broken upon delivery.

It is now the 30th of October, and I am still waiting for a response or a phone call from Leroy to explain where my replacement door is, and why it is taking so long.

I have sent numerous emails to them, I have phoned both the store and the manager who I spoke to when I reported the broken door, and even visited the store.

They do not reply to my emails any more, and when I phone, it either goes to voice mail, or the call center agent puts the phone down in my ear (I am very calm and respectful on the phone).
