We visited Bank Of america in CHicago, IL to deposit a check that I received as part of my mother life insurance from the social security Administration in Mexico. The transaction supposedly went fine and the bank credit our account for $3, 768.99 US dollars. A few days later we received a letter from the bank telling that the funds deposited on the account were deducted because the check was listed but no enclosed. We inmmediatly contacted the bank but they gave us a different version, they said that they sent the check to processing center but they couldn't get the check paid for the bank in mexico and the original check was sent back to us, but never received the check. When we tried to call them again they maintain the version that the check wasn't enclosed. WHat can I DO Against them
