Bad experience

I Just had the worst experience with this company Leroy Merlin in Little falls. They sell items to you and then when you collect they come back a hour later and tell you they don't have stock they try and sell you a display item that's incomplete but with no discount. When you want to see the manager he is on tea and nobody is willing to help. I cancelled the order and waited some more to get a refund. This is not the first time it happened. will not recommend to deal with them
