Bank of America contacted me and issued a new credit card because " an undisclosed merchant '' had compromised my data. When I called and requested the name of the merchant, they said they did not know and I would have to call XXXX. I asked to talk to a supervisor who told me that calling XXXX would be futile as they also would not tell me what merchant had compromised my information. I want to know what happened so I can determine whether I want to continue to do business with the merchant.
