Incomplete Order! The parts are labeled A, B, C, D. "A" is the right arm bracket and "B" is the left arm bracket. I received three "A" brackets and one "B" left arm bracket, (photo), No way to use this chair. I would appreciate a "B" arm sent ASAP or please advise what will be done to correct this problem so a positive review can be posted. Received the missing part & the customer service was awesome. The set looks great in my courtyard and the chairs are very comfy. Highly recommend.
