Bank of America Credit Card Complaint

Bank of America Credit card department,

Transaction issue Minnesota

I did not recognize a credit card charge and disputed the charge. I received a letter informing me that the charge is valid, without additional detail on who the merchant was. I still do not recognize the vendor and still do not know what this charge was for. The charge is only $5.00 but if this is because a hacker is siphoning off a few dollars off of everyone, then it still deserves to be investigated.
