Leroy Merlin Greenstone

I found a product on their site that I liked. I proceeded to select a store that indicated that they had stock and subsequently paid for the order and delivery. The item was supposed to be delivered on the 3rd of May as shown on the order status within my online profile. I did not receive delivery on the date stipulated. I called in on the 4th of May to enquire and was told that the store would contact me and they didn't. I called today, being the 5th of May saying the store hadn't contacted me. The agent assisting me advised that I stay on the line while she calls the store. She later came back to me saying that the store had no stock of said item. This is poor customer service. Leroy Merlin Greenstone, please do better.
