Hello. Recently I received a letter stating that my payment would be "zero" for the next year. This is most likely due to my change in income and the fact that I have other student loans that I now have to pay in addition to these. When it came time for my automatic payment to be deducted, they deducted $18.12. When I tried the "chat" feature with them, I was told that there was an error with my letter and that $18.12 is the new payment. I have yet to receive any letter indicating the change, but I still have the one that states "zero" is due for the next year. Who can I talk to about this, to have them honor their letter?
