877-459-7301

Identified themselves as Dell Finance.
Wanted to confirm some info on a order for
15 cameras that were going to be placed on
my business acct with them.

I don't have an account with them.  Told me
I should call Dunn and Bradstreet to make sure
no other accounts had been opened.

D&B wanted $799 for their alert service.

Sounds like extortion to me.

Identified themselves as Dell Finance.
They reached my accounting department to get authorization to ship product and bill our Dell account.
My accounting department asked who ordered and what was ordered. "Dell Finance" would divulge no information.
I confirmed with the Partners in my firm that they did not order anything or open an account.
I called 877/459-7301 myself and spoke to Mollie.  She would not give me any information, only that she was part of the fraud department and the account would not be opened up in my company name and no charges have been made.
What a scam!     Stay Clear!

Got a voicemail from this number -- caller identified himself as Dell Financial Services and wanted me to confirm an order and gave a reference number.  Called back -- no such confirmation number and nothing under my name.  Definitely bogus but I can't figure out what the scam is.

Not bogus, this is a legitimate number and it is the Dell Verification department calling to confirm an account, shipment or order.  Do not ignore it, stick on the line and force them to tell you why they called you.  I called with my ID theft investigator on the phone with me and after a run around finally confirmed there was an order place a month ago.  They don't call for the hell of it.  Call the number from the website, suffer through the transfers, but you will eventually get someone to admit they called you.

Or... wait for the bill to come in the mail and address it then, or when it goes to collections and you fail a credit check for something legitimate.  I wouldn't recommend that...
