Four days ago I was doing some searches on UA.com to check if flights were available, times, etc. I ended up taking one of those dummy bookings all the way to the final payment screen.

Today, I logged in and see that the dummy booking is in my list of upcoming flights. Not only is there, but it is booked in full fare Y, has a PNR, seat assignments and the flights are supposedly ticketed and confirmed. The flights are both marketed and operated by MS but I can't pull up anything on their website with the UA PNR.

I cannot view the receipt or email it to myself. Both give me an error. I cannot find an eticket number.

None of my credit cards have been charged.

How should I proceed?
