Computer not received in two days

I was promised delivery of  a laptop within two days. It did not arrive today. Looking at the UPS tracking, it was sent via ground delivery, which is extremely slowly, so  it says it will arrive nine days after I ordered it. If I had known it would take that long, I would not have ordered it at all. I called Dell  and spoke to at least 5 different people over the course of an hour, none of whom helped me and transferred me to someone else, and finally Customer Care was closed. I need this laptop urgently and still do. Dell should immediately overnight air express send me another one and retrieve the first one through UPS, since it was Dell's error in the first place. I am thoroughly disappointed by the way Dell has handled this, first, by Dell's error in send it the incorrect way, and second, by the totally unprofessional and inefficient customer service. I want to know how Dell is going to make this right for me.
