Trying to locate an instruction manual to put 3 shelf bookcase together. Purchased this from the Goodwill that was sent there from Target with no instruction manual. There are so many peices that it really is difficult to figure out how it should go together. I am on day 2 of trying to get any information. I have called Target several times; to only get the run around from various employees and departments with no luck. I have tried to look up the company with no luck. Anything leads would help. Thank you
