AES/PHEAA Student Loan Complaint

AES/PHEAA Student loan department,

Non-federal student loan Can't repay my loan California

I took a private loan out during my undergraduate courses. The original loan was for approximately $12000.00. The original loan was taken -/-/- and I started to make payments -/-/-. As of this date I am still at $16000.00. This does not make any sense to me as I have made consistent payments since that time. Additionally, I made a payment for my monthly bill before the auto deduction occurs due to moving and wanting to ensure that my payment was made. They still took out the auto deduction causing me to overdraw my bank account and receiving additional NSF charges. I would like for your agency to look into their practices as I really can not explain why I am still no closer to paying off this loan than I was -/-/-. AES Account # : -
