Navient Solutions XXXX Inc. ( formerly XXXX XXXX ) locked me out of the online payment system without notice, suspending my ability to make payments on my account, the reason they stated for this account suspension is because I sent XXXX XXXX a letter in XXXX of 2006 asking them not to contact me my phone about my account. I have been making online payments since 2006 with no problems until now. I have receive NO correspondence from Navient about this action. My account was turned over to their litigation department and I believe they are trying to force my account into a default status.
