B&W 805 Sig Problem.

hi guys.wanted to share this with you all. i purchased a pair of 805 sig. they came in with a manufactures defect. waited 6 months for the 2nd pair. same problem with the 2nd pair. clearly their fault. now b&w wants to blame it on the shipping company.who can i speaker to above the service manager of b&w/rotel to get a good pair of speakers i purchased 6 months ago. the tweeter cap is not set properly, sticks out about 1/2 inch on the right side of every speaker. i love the speakers but i am pissed.thanks.
