Until this week I had never heard of WFNNB. They sent me two letters this week. The first said that my METROSTYLE credit card account was suspended due to potential security concerns and/or irregular credit card transactions.
The second letter thanked me for applying for a metrostyle credit card account, but that I had been denied because "information we obtained from the credit-reporting agency indicated potential fraudlent activity." They gave Experian as the reporting agency. I contacted them and got my credit report.
