Leroy Merlin online

I love Leroy Merlin stores, but online shopping is a waste of time and money. I purchased a cordless vacuum which arrived quickly, on opening we saw that every coloured surface was sticky to touch and came off with the plastic wrap. I phoned and asked for it to be returned and my money refunded. I have placed at least 4 calls and each call I was promised service and call backs. Nothing has happened. An email was received about my refund in progress, but the product is here and no refund in sight and no communication either. I have had problems in the past but gave Leroy Merlin a 3rd chance and they dissapointed once again.
