3 exchange in 1 year with the last bed delivered damp and moldy

To cut the story short, i have exchanged the Sealy bed I bought online twice and the 3rd time which is today, I requested the change of the brand to Cloud Nine and guess what, they delivered to me a damped bed that is moldy. To say I am ****ed would be an understatement. When do I sleep now? For the entire year this company is toying with me and i'm damn mad! I paid a good money to get a good quality bed and what they do is play games, isn't there a supervisor that checks products that get delivered to customers or you did this on purpose?
