Terrible service from Leroy Merlin Marketplace

I placed an order online for a headboard on the 5th April . I honestly do not recall reading anywhere on the fine print that the order could take up to 15 days to be shipped to me! Had i know that i would never have placed the order but here i am . I called the call centre and i initially spoke to Winie to find out when i could expect delivery. She was not very helpful to be honest and placed all the blame on the supplier and me saying it states on the website that it can take up to 15 days to be shipped. I am purchasing a headboard from Leroy Merlin i am not really interested about the supplier. I expressed to her that i am travelling alot and would appreciate the delivery to be sooner rather than later. All i got from Winie was a bunch of emails with very little info. She only bothered to call me today after i called yet again to ask what is happening as i received an email from her say that the order had been returned. She was very quick to tell me that the courier could not get hold of me. Funny thing is i was at Home all of Friday and did not receive one call to confirm delivery. This is shocking customer service to say the least and i lesson well learned never to order anything from Leroy Merlin online EVER again! It is 15:29 and i am yet to receive a call from Winie to update me on the courier.
