Synchrony Bank Credit Card Complaint

Synchrony Bank Credit card department,

Identity theft / Fraud / Embezzlement Virginia

On - - I received via US mail a Walmart MasterCard. This is a real credit card, not an application or a temporary card. I have NEVER requested or applied for a Walmart credit card. Naturally I destroyed the card. On - -, I received a bill for this credit card for purchases made at a - in -, NY. I have never been to -, NY. This is clearly an attempt at identity theft. I do not understand how someone could use the card or the account number when it was never activated. I have written to Synchrony Bank ( who issued the card ) reporting this misuse of my personal information and informed them that I refuse to pay the bill. I also closed the account via their telephone system. My concern is that, because the credit account was apparently opened without actually using the card, further purchases may occur. Also, a different Walmart/Synchrony bank credit account, albeit with the same opening date, shows up on my credit reports, so apparently there are - accounts I have to deal with. I am very concerned about this and not sure how to stop the misuse of my personal information.
