Hi, I received my sofa a few days back and assembled in yesterday on weekend. While assembling, I found that both part Cs (the sides) are crooked and would not match to their desired places. I had to leave couple of bolts and nuts because it was impossible to align them. I am disappointed with quality assurance. Since it was hard enough to unpack the box, I certainly cannot pack it back. So please take an 
initiative to take this product and issue me a replacement or refund. It was a waste of my few hours browsing all the online sofas you have and reading reviews. Thank you for your help.
