Navient, a company who took over for XXXX XXXX loans I have, calls me up to XXXX times a day, calls within XXXX hours of each other due to a loan being 2 months past due. I had requested paper billing so I could mail in Payments and have n't received them so I did slip. I notified them when a check was mailed with the check number and amount and the calls stopped for 4 days. The account is up to date now with next payment due XXXX and they called again at XXXX Sunday night. Enough is enough. Enduring multiple phone calls a day starting daily at XXXX and going think XXXX had finally stopped and now they are apparently starting again.
