I am a cosigner on a student loan for my son who became financially unable to continue payments. I went to AES in XXXX 2015 with a new direct debit form and again in XXXX with the same form. They continue to debit an account that has no funds in it, and every month my son gets an insufficient funds charge ( {$30.00} - which I pay ) and every month I get a threatening letter that my credit will be ruined and then I pay online through the account I am trying to get directly debited and then I call again and am assured the following month the correct account will be debited. I do n't seem to have any options, as written and aural correspondence has been ineffective. An attorney would cost more than the bank is charging and losing a .25 % interest rate just adds additional long term cost to the payments.
