Empty promises

I bought a office desk from Leroy Merlin online and on the website, under my orders the delivery date showed 02 February 2024. Around 17:00 I decided to call their customer service since it was getting late and my order wa not there and no update whatsoever, the lady I spoke to on the phone told me that my order will be delivered by the 07th of Feb latest. So I asked her, why does it show the 02nd of Feb on the website and she said it's a system error. Now the question is; why do you make promises you cannot keep. It's easy to place a order but your delivery and order tracking system is extremely bad. Maybe you can learn a thing or two from TakeALot, they always deliver on time.
