there should be the location of whichever atm the unauthorised transaction was made at..this should also show in the sms frm the bank that you recieved..as any atm has a camera it should be easy to find out if smbdy did withdraw at that time and day using the atm or to prove that your husband or you didnt use the atm going thru the camera footage..ask the bank this and dont hesitate to report this to the police..perhaps it better safe..mayb sombody within the bank playing games.
