Moldy furniture

I placed an order for a headboard on Leroy Merlin early July. When the order arrived a portion of the headboard was damaged as a result of mold, they wereinformedand pictures were provided on the day of delivery. Initially they agreed to swop it out, 2 weeks later when I followed up the response had changed to there doesn't seem to be much damage. Mold spreads and pictures don't lie! Leroy Merlin, please pick up your piece of **** and refund my money! The constant back and forth with your consultants since the 25th July is ****ing embarrassing as far as customer service goes!
