Montgomery Wards fraudulent charge on my credit card account Monroe, WI Nationwide

I found a fraudulent $1 charge followed by a fraudulent $300+ charge on my credit card for this outfit in Monroe, WI called "CB Montgomery Wards."  The charges were made the very same day.  My credit card company conference-called them with me on the line; the folks at "Montgomery Wards" were unable to trace any purchase by me, shipment to my address or use the credit card number to even discern what was purchased.  Scam!

After the call with the Montgomery Wards representative terminated, I was quickly transferred to the Fraud Protection area of my credit card company, where they flagged the purchases, waived the charges and closed my account.  A new credit card account with new numbers will be issued to me soon.

I caught this before my credit card company did.  Not sure whether they would have or not.  I'm glad I did.  Scammers.

I'm left wondering how someone got my credit card information to manage this purchase.  The card has not left my possession and there are no other joint-account holders.
