I have been disputing a CC transaction error on my United MPE card for the last few months, and it's taken a bit of a bizarre turn. Right after a trip, I matched up bar receipts, and noticed a $32.00 charge I don't recognize and can't find a receipt for. No biggie, I call United customer service, and they happily put a hold on the amount to investigate it.

After a few months of letters letting me know about the progress of the investigation, I receive a letter today that says that they have finished the investigation of the $32.00 dispute, and they consider the dispute resolved because my credit card was not reported as lost or stolen.

So, they attached a copy of the sales slip, and I immediately notice a few things that are very wrong with it:

- Card type: Master Card (all of my Chase cards are Visas)
- Acct #: XXXXXXXXX???? (four numbers that don't match with any of my cards, Chase or otherwise)

What happened? (1) I have no idea why the Dispute department missed these details, and (2) How did someone else's card charges end up on my account?

I just called the Fraud Department, but they were no help. I will call back to get the Dispute Dept. tomorrow when it's open.
