Poor online and delivery service from Leroy Merlin

I am very disappointed with my current online experience with Leroy Merlin. I placed an order for 5 items online from Leroy on the 17th of October with an estimated delivery date of the 23rd of October. On the 22nd of October I only received 2 out of the 5 items. The remaining 3 items still showed a delivery date of the 23rd. However the 23rd came and went with no update from Leroy. I checked the online system the following day and the order delivery date was mow updated to the 24th of Oct. Again the day went and no order was delivered. I called Leroy on.the 25th to find out what was going on and I was told that the IT team did not push the order through for picking and also now 1 of the items is out of stock. Flora assisted and managed to get the order pushed for Dispatch. The delivery was now estimated for the 29th of October. However again I was told by the courier company they were given the incorrect address and the correct address is not on the route and they can only deliver on the 30th. I should never have placed my online order with Leroy and just stuck with Builders Warehouse. I never experience this kind of poor customer service from them. I will never order from Leroy Merlin again after this experience.
