They took my social at the beginning of the call, and after I explained what I wanted the agent asked some income verification questions, then said she would put me on hold to see what she could do.
To me, this (bold text) would have been a clear warning sign. I don't know how BOA operates, but I've dealt with other banks about credit limits on newly approved credit cards; however, all those were discussions with the special credit approval department agents, i.e., never the regular front line customer service agents.
