Here is some real advice on how you can improve your experience.
First and foremost, what kind of company do you work at? Do you have a Dell sales rep?
If you have a Dell sales rep, explain to him an issue you are having, hell even if it's a fake one. Ask if he can direct you to a number that you don't have to wait 45 minutes for (ask nicely of course). Wait a few days and send him an e-mail saying that his help was invaluable in getting the issue addressed, blah, blah, blah. Ask for his supervisor's e-mail address so you can let the supervisor know how pleased you are with the service. Send the supervisor an e-mail about how wonderful your sales rep is and CC the rep on it.
You will have that sales rep wrapped around your little finger for good. My company buys very little from Dell, but I used the above scenario and my Dell rep calls me from time to time to see if I have any issues and they never include hassling me about whether or not I'm "planning any major purchases", etc.
If I do e-mail him with an issue, I get a phone call in a matter of minutes nine times out of ten.
I had a MOBO issue on something that was out of warranty. The MOBO had some manufacturing issues (transistors if I remember correctly) though so I figured I would give it a shot. I e-mailed my rep at 4:30pm EST and he called me back right away. There was a new mother board waiting for me (shipped from TX) when I got in the next morning at 10:00, free of charge.
I'm always the first to complain all the way up the chain-of-command when I get horrid service, so when I get good service I make sure to send kudos up the chain as well. It has paid off about ten-thousand times over.
Lacking a sales rep...once you do finally get in touch with level 2 tech support, do the same thing I mentioned above for the tech you deal with. I have the e-mail of 3 different Dell techs because I have done that and those guys always know the right people to call.
Having said that, I have always had nothing but wonderful support from Dell. From my personal computer which got fried when our house was struck by lightning (new MOBO, RAM, power supply, CPU, basically everyhing shipped to my house in a few days and I never even had to return the old stuff), to business issues.
Compaq is far and away the worst I have ever dealt with. When I was in the Marine Corps I had to deal with them and I hated every second of it. I rarely got someone that spoke English well, so I would go through tech after tech until I could carry on a conversation with one of them. I would politely but firmly tell them to get me someone that I could understand.
Of course, this was all before I came up with my plan.
