Query: disappointed

I bought on October 19, 2011, two headsets and received on December 26, 2011 only one, moreover, sent a package without any protection and after the attendant phone service was very bad mannered saying only send the second receiver ear if I took a prior claim, that is until now not received the headset, I've paid more than 2 months and nothing yet. How should I proceed?
