Award winning Dell support?

My company purchases about 30 high end pc's every month, for the last 5 months, rolling out systems. Why lately are techs so darn rude, and refuse to be of much help. They claim the system owner info is not available(this has happened 5 times in 2 weeks(yea... a lot of defective parts lately from the factory)). They want us to log into the site to change the owner info?? Excuse me? I bought the systems from you, and I am NOT changing 30 systems owner info when I am quite sure you can assign the info. Oh we cannot be of service without the correct information. Oh? Well I have the purchase order, the invoice, and order number, but you can't seem to locate anything? When you finally DO get them to admit you actually have the system and are the rightful owner, then they ship you the wrong part THREE TIMES.

Thank you for causing me an extra 20 hour grief every week during the last month. You deserve an award all right. Anyways, I'm done ranting, anyone else see a dramatic decline in service in the last 4-5 months?
