Prism/CBSD was on my credit report this a.m. and, after 2 hours of investigating I got to the bottom of it. The credit card numbers beginning with 525650(10 more numerals follow) belong to one of 4 companies, all are under the banner of Citibank. These companies are; West Marine, Goodyear, Gateway, and Herzberg (jewelers). If you didn't open an account with any of these companies, as I didn't, you can call 1.866.510.2761 and report the fraud (after verifying that they have an account in your name with your social security number). If you are uncomfortable calling this number and giving out your social, you can start by calling the Citibank fraud number listed on Citibank's web site (fyi, that number is 1.800.950.5114) and tell them the first six numbers of the partial credit card account number, and they will tell you which company issued the card and how to contact that company by phone. Good luck! It worked for me.
