Query: Service problem

While I enjoy the comfort and clean sound, the extension cord was defective from the package. The pigtail on the speakers is too short to use exclusively. All attempts to get a replacement without delivering the cord to an authorized repair facility failed. The closest facility is 3hrs. one way from me and mailing was not an option, nor is the extension available as an option. Sony's repair service policy is unacceptable!
