Lack of Response - Missing Item at Shipment

I wanted to find somewhere to air my frustration with Dell.  I ordered 6 monitors and 3 desktops in late March.  One of the monitors was missing the correct power cord.  I have emailed and/or called 7-8 times and still do not have the proper power cord.  Time on the phone is at least 2 hours, and they just don't seem to really care.

I have purchased Dell equipment since my first desktop in 1997.  I have a related company that purchases over $100,000 a year from Dell.  I am deeply disappointed at the lack of follow-up and resolution to my issue.
