Shocking online service from Leroy Merlin

Shocking online service. Today it took me about 2 hours to put together an order of 4 items because of the incredible slow response time for every screen, and the strange wys certain things .like "Add to Cart" are implemented. At last I got it all ready, went to checkout and was told that "certain items cannot be delivered to this address" So I called to find out why this message? Which items could/not be delivered to me? What other address I could use to get the order delivered? The person who took the call could not answer, and said that several reports had been made back to online staff. I asked to speak to her manager, I hung on for another 10 minutes, till I ran out of minutes. I shall never try to order from Leroy Merlin again.
