Calls, leaves no message. Sales company of some kind when I called back, didn't stay on the line long enough to listen to the whole spiel.

This company has called me about a dozen times over the past few months.  Each time I tell them I do not want the warranty and to stop calling me about it.  I've been called the last four times by "Steve".  Before I can finish my sentence "Do not call me again", he hangs up the phone.  I guess because he doesn't hear me say don't call me he figures he can call me back.
