Navient Student Loan Complaint

Navient Student loan department,

Non-federal student loan Can't repay my loan Texas

I have been trying to responsibly manage my situation with Navient, yet every time I call them and I speak with someone they ( the agent ) end up hanging up on me. Today I was being asked some questions that the agent told me could potentialy lower my monthly payments, but when I told them I was un-employed the last thing I heard was a grunt and they hung up. This is not the first time this has happened. On a seperate occasion last week I told them I was not capable of making large monthly payments, and when I was asked how much I could pay, I responded to the agent and he told me he would return my call. I never received a call from Navient in regards to that conversation. Now they are telling me that a payment I had agreed to make with them did not go through. I am trying very hard to be responsible given my situation with un-employment, while also trying to avoid any kind of delinquency but Navient is beginning to demonstrate some rather sketchy behavior. I feel helpless in this situation because I am trying to call, and I am trying to reach a solution, but I am recurrently being hung up on, and when I try to call back no one answers.
