While deployed I attempted to make a larger than normal payment to a lender which resulted in my overpayment of what the lender was allowed to accept on a monthly basis. This resulted in my cancellation of recurring bank allotments to the lender under the impression that I had paid my account in full. The lender failed to notify me not only that I had over paid them but that they were charging me fees for the overpayment. This resulted in a 120 day delinquency being reported on my credit report. Once I returned from XXXX I received an email from an individual from the lending company that was assigned to identify the reasoning behind my large gap in payments after a previous perfect payment history. Once he informed me of what had occurred, I repaid the past due amount in full and the account was later closed
