Moldy mattress used ONCE

I bought a lawerence leather sleeper sofa about 2 months ago. Opened it after it arrived. Put the matresss protector on it. Closed it up. Just opened the pullout sofa and the bottom trim is covered in mold.. I am pissed. It better be removed with a full refund this week. I also never received the feet to the matching chair after contacting customer service about 3 times. Do not buy from bobs. I paid full price for all of this crap. Now I know better. Refund or lawyer. Not ok or healthy to have around my family.
