Material floors - and no refund policy from Metro

I bought material there and not even 3 moths later there are floors in the material. (it is upholstery material), so it was not visible immediately. I went to metro, and they said there policy is no returns after 7 days. The upholsterar was not even done with the work in 7 days. Now I am the one loosing all this money, and need to replace my couches within 3 months. How is that fear - and they just walk away and I need to take all the lost.
