Placed an order but it doesn't show up?

I ordered an Inspiron 14 at approximately 2pm, and when I put in the payment, I got a screen showing "Thank you for your order" so I assumed everything went through OK. However, I never received a confirmation email or message at all, and when I tried to look up the order status, it says that I have no orders. (??) 

I then attempted to look up the order using the Purchase ID that I was given, but it kept saying the ID was invalid.

For reference, the Dell Purchase ID that I was given was < Private Transaction id removed.TOS73>

Then I tried to contact Customer Support via phone. The automated system directed me to enter the Purchase ID and phone number, and each time, it said that it could not find anything under those numbers.

My payment method was never charged.

I am assuming that my order did not go through for some reason / there was an issue of some sort? I'm just trying to get to the bottom of what happened and want to make sure that it is indeed the case that the order did not go through, as I am now no longer interested in purchasing this computer and would like to purchase a different one elsewhere. Your assistance is appreciated.
