Access Group Student loan department,

Non-federal student loan Dealing with my lender or servicer Kentucky

Lender : Access Group ; Loan service provider : -Private student loan. My monthly payment amount adjusted ( based on repayment schedule ) and I contacted customer service via telephone to verify the new payment amount ( then made a payment for that amount ). The following month I received a statement indicating that I was $.00 delinquent on my account and that a $10.00 late fee had been assessed. I then contacted customer service via phone again and was told that my $.00 overdue amount had exceeded my contractual 15 day grace period and that they would not waive the late fee.
