HORRID online shopping

There's a particular yellow and black coloured competitor which has a wonderfully spotty track record or customer service, to the point that with 4 of them within driving distance I still rather opted to order from Leroy Merlin online.

I mean, it can't get any worse right? well this is what happened...

7 June: Order made online, and paid. A few days later: I get a call saying one of the items is not in stock, asking me if I want to wait for it, I decide sure because this is my first purchase with them, why not save them the extra delivery costs. BIG MISTAKE. 30 June: I call to find out what is going on, I get told that I the representative at the store will call me back. I never get a call. 2 July: I call again to find out what is happening, I get told that the one item is still on special order and they will ship everything else so long because it's been so long. 9 July: send email to their listed email address on the invoice: *** trying to lodge a complaint, no acknowledgement of receipt, no response at all. 14 July: still no products at all, and ZERO communication from Leroy Merlin since 2 July.
