Mouldy Jolly Jumper moses Basket

Hi Ladies just wondering if anyone else has had any problems with the Jolly Jumper Moses Baskets from Farmers?? I purchased one about 6 weeks ago and left it in the box in our nursery as baby is not due until Oct. I have opened the box approx twice since we got it just to check mattress size so I could buy some linen. When I opened the box yesterday I was horrified to find that the ENTIRE basket was covered in a green mossy mould with a toxic smell. Our flat is really new, clean, warm, dry & we don't have any problems with mould so I am confused as to how this could have happened? I took it back to Farmers and got a refund but just wondered if anyone else has had the same problem?
