USAA Savings Credit card department,

Identity theft / Fraud / Embezzlement Pennsylvania

I have paid - on to my USSA credit card on -/-/-2016. I paid through bill pay through my bank. I have a check # and confirmation #. I have called USAA over 5 times in the last week and they continue to tell me that it has not been paid and to contact my bank. I have since received a $70.00 interest view. I have requested to speak with a USAA supervisor several times but have not been able to. I have provided USAA with the check number, name of bank, bank contact info and the confirmation number and still USAA refuses to assist me in getting this resolved. In a few days I will acquire a late payment, because they have not recognized my payment of -. I also want to make sure this does not negatively impact my credit
