Not getting what I paid for!

I upgraded my contract online and part of the deal was a pair of earphones included with the handset, It took over a month for them to deliver my new handset (due to stock shortages, no one took the time to notify me of this!) and when it arrived it never included the above mentioned earphones. on contacting Samsung I was told they could not assist me as this falls out side of the promo time, no one calls you back!
