Citibank Credit Card Complaint

Citibank Credit card department,

Convenience checks Nevada

After checking my Sears Credit Card online statement in - 2015, I noticed an unauthorized Balance Transfer Convenience Check transaction ( ck # - ) that was posted to my account on -/-/2015 in the amount of $400.00 and a $16.00 balance transfer fee. I sent Sears Credit Card a letter stating that I never authorized the issuance of any type of balance transfer checks for my credit card account nor have I ever received any type of balance transfer checks in the mail. I requested that a dispute inquiry be opened since I was a victim of balance transfer check fraud. The bank sent me a copy of the balance transfer check image which was not made out in my handwriting or did it have my true signature, the signature on the check image was forged and completely different than my true signature. On - -, 2015, I sent Sears Credit Card a certified letter w/return receipt ( USPS Certified Label # - - - - - - ) stating that I was indeed a victim of balance transfer check fraud and requested that they open a formal dispute investigation. Since then I have not received any type of formal dispute investigation acknowledgement.
