CBNA is Citibank. They are the actual bank that services many store brand credit cards like Best Buy, Goodyear, Target and so on. You may have a store brand card that is backed by Citibank, but the name is being assigned incorrectly by the credit bureau computer. If that doesn't answer your question, get your full credit report at www.annualcreditreport.com which will have the phone number for the creditor, and you can call them to clarify.
