My Dell horror story:
I had a Vostro 1500 with an HDD that went bad, probably after it was poorly handled by TSA.
First they argue what's wrong (I told them my HDD, they screamed RAM. I was right). I had an overnight parts next day service plan. They shipped RAM and sure enough it didn't change the situation. I finally got the HDD a day or two after calling them and saying RAM didn't work, went to replace it and . . . oops, their screws were stripped. Okay, call them and they say a technician can handle that (uhuh, sure . . . ). Low and behold the technician looks at it and says "uh, I can't do jack about stripped screws" (no, really? Say it ain't so!).
Okay, so now I'm told by Dell the replacement HDD needs to be shipped back in a different box from the laptop and they'd fix the laptop at the factory. Checked on their return form that I wanted it back only when it's fixed.
Week later, get the laptop with the screws fixed . . . but the HDD wasn't. Lovely. Call them up and the part was out of stock. Called them about every day . . . for three months they dragged their feet.
When I finally got it they shipped it standard ground to add insult. They were absolutely terrible to work with.
What I'm trying to decide is whether their support is just that bad, or if it was an issue because they forgot to affix the express service code to my laptop. Either way it's their fault and the service I received was so awful I doubt I'd want to buy another again (if I do I'll use a squaretrade warranty instead), but it's either that or the fact I didn't have a sizeable business agreement with them. I seriously find it (un)funny how people that get their laptops through their employer (or an employer affiliated offer) when the company they work for absolutely freaking huge have near zero issues with Dell, but those that don't seem to have never ending issues with support IME.
And let's be clear -- this was Dell Business I purchased through since that was the only way to get the Vostro line. This was apparently their supposed high grade all US support at the time.
