Support is not supporting

The company I work for has used Dell for as long as I can remember, and you guys have always been great. I placed a personal order through the employee purchase program and have not received that same level of support. I've come here to see if I can finally get some help.

I ordered a new computer that was supposed to arrive tomorrow, but the order is apparently "invalid" - what that means, I'm still not sure. When I called the order support number that I was given by the chat agent, I spoke with a woman who called herself "Mary". After about 10 minutes of attempting to get it resolved, I eventually asked to speak with someone else because I was having a very difficult time understanding her. She proceeded to call me racist and then transfer me to the main line. I called back 4 times and managed to get her every single time, although the last time she called herself by a different name. Of these times, she hung up on me twice, put me on an infinite hold once, and then I ended up hanging up on her the final time out of frustration. I repeatedly asked for a manager or to talk to someone else, but she insisted on name-calling and cyclical conversations.

Really and truly, I wanted to get this laptop because I know that you guys make quality product, but after this nightmare, I wouldn't suggest a dell purchase to anyone. I never even got notification that the order wasn't going to process. I luckily had chatted to get the shipping address updated. 

Sorry for the rant. I am just dumbfounded by this situation and needed to share.
