BofA bought MBNA a while back and the transition was NOT smooth. What they said on their website did not match my experience during the change.
Ditto, they bought Nations Bank about 10 years ago. They still have not integrated their military banking with the rest of BofA. If I have a question about my account they have to call San Antonio to find out because the systems are not linked at the teller. You have to go over to the customer service desk to get them to access my info. This month I just opened up a bank account with a local bank in GA and the manager knows my name, my wife's name and my son's name. Can't say the same about BofA. Their too big to care as another poster mentioned.
