dell management

I need to contact Dell management.  Technical Support and Sales and "Chat" are not options, and there seems no email address or any way to contact anybody with proper accountability. That seems bizarre for a huge company such as Dell. No large company can operate without management or Directors,  yet they seem totally invisible. If anybody has found a way to get straight to somebody in authority I (and no doubt others) will be very grateful if you could post the method. Many thanks.
