Home Trends couch slipcover- turned my couch!?

I have a cream colored suede couch....bought a chocolate colored suede slipcover for it at wal mart...their Home Trends brand. I just took it off to wash it....and my couch is stained all over brown! theres wrinkles where it wasnt stained so that looks even worse! Im SOOO pissed bc i bought this cover to keep my couch clean and now its ruined. I tried cleaning and didnt help at ALL. Is there anything i can do this is very unfair!
