We accidentally missed a payment in XXXX. We are approx. XXXX dollars past due as of XXXX payment. When we got a reminder in the mail and were unsure of the reason we called them to verify, discovered our mistake, confirmed the amount and said we would make good on the past due portion during our regular XXXX Payment which we then set up with the bank to go out on XXXX XXXX. However, since our self initiated call, we have received XXXX calls daily from Navient, trying to collect this past due payment. We have explained ourselves repeatedly and asked the calls be stopped. XXXX we were told the calls would stop for five days and they would put a note in the system. This has not happened. The calls have continued at a rate of XXXX times daily. We feel harassed, we are losing valuable time on the phone in repeated explanations and we have told them to stop or we would file a complaint. They have not stopped. This is our complaint.
