Ally Financial has been charging a fee for late payment when I have been paying the amount due as shown on the online summary. So instead of allowing me to pay for the amount due and also any additional fees on the account they only allow the amounts paid to apply to the principle and do not tell you or advise you that any overpayment is only applied to principle and will not be applied to fees. They then XXXX fees based on the original infraction without telling you.
