Street Style Store — exchange product not received and no confirmation mails

I had returned a pair of slippers 2 weeks ago as i received the wrong pair. After multiple tries to contact them i filed a complain here and finally got a call back from the store and the return was picked up. Its been 2 weeks since, and i haven't got a confirmation mail nor have i received the actual product that i ordered for. I would strictly like a refund if i'm not going to receive the product within this week. Its the first time i have ordered and already so many issues. Never ordering from here again.
