Leroy Merlin displays are misleading

Greenstone branch has misleading displays. Their staff drills holes in a clip on blind, making customers think it can be wall mounted. My sister in-law who has no DIY knowledge bought them without knowing, then had to get someone to "make a plan" to get them installed. I tweeted them with NO response. Absolutely misleading, **** advertising. Disgraceful that a big company can engage in such practices, and the sales person even had the nerve to assure her that yes, it can be wall mounted! Bottom line, don't believe anything this dishonest company or its sales people tell you!
