Poor Quality Stove (Leroy-Merlin VS Ferre)

Their products are very poor quality. I ordered a stove and it is super light (4 plate with oven). I asked to return it and they said they would charge me 10% for "changing my mind" I decline and eventually accepted as they only respond to your emails once a day and I need my money back to buy a new store else where. I agreed to the 10%, 4 days later the stove is still with me and no confirmation on when they will collect. I wish I had had a look at their online reviews cause it seems their customer service and quality of products are know for being terrible. Please come and collect your stove and give me my money back. I promise to leave you alone after that.
