Shocking customer service at Leroy Merlin

I ordered 2 x 1 000 litre JoJo water tanks from Leroy Merlin online, after I made sure that they had the colour I wanted (wintergrass) in stock at the Fourways branch. They said delivery would take place about a week later, on 16 February. I phoned on 17 February to find out why no delivery had taken place, only to be told that they did not have stock of the colour I wanted. They offered to deliver me green tanks, which is the last thing I wanted. Pathetic customer service, nobody informed me at any time that they did not have stock or that the delivery would not take place on the date indicated on the online tracking. This is over and above the shocking service that I experienced at the Fourways branch, where a salesman left me to attend to another customer and just never returned. I left a trolley full of plumbing accessories to go and buy at Builders, where I always get good service. This is a company that will never see me again.
