Was really excited to get this couch, as I had bought a chair from this brand on Wayfair, and has been a great addition. But the couch came with missing pieces ( see photo) and missing assembly instructions. Even though Wayfair has a missing parts policy, how am I supposed to provide part numbers when I don’t have the instructions or information of what the parts  part numbers are Well see if I actually get the correct parts. If not I’m stuck with a half together couch that sits on the floor.
