How do I contact Upper Management at Alienware - Please Help

I need to know how to contact upper management at dell / alienware. I am not gonna disclose the full story here in the forums but I will say that I am very angry and disappointed at how my whole repair process has been handled. I have had my motherboard replaced twice and my optical drive and heatsink replaced once. My warranty is about to expire and I feel like they are just trying to buy themselves enough time for my warranty to run out so they dont have to deal with me. If anyone knows how to contact upper management via email or phone please for the love of god tell me.
