Remember when i posted a warning a few weeks ago... well

I just got another call from another company this time agents travel asking again for bank numbers!!!!!!!!!!! I could not believe it! No I am worried that bank of america is giving out my info! This company claimed to have gotten the info from a company I bought something from my checking account! Never! I never use my checking account except for bills!!!!!!!!! what do you think? When the company was fleet I never received these calls! Now that it is bank of america I get 2 in a few weeks!
