I signed an agreement to payoff my Citi student loans over 15 years when I started repaying my student loans. During that time, Citi student loan was servicing XXXX of my loans, # XXXX & XXXX. My total monthly payment until XXXX 2015 was XXXX ( # XXXX = XXXX and # XXXX = XXXX ). In XXXX, I paid off loan XXXX. Citi then sent me an XXXX statement showing that I owed XXXX for loan # XXXX. In XXXX, I called servicing and asked why my payment for XXXX had increased. They initially told me it was due to a mistake on their end which meant that at the current rate I would not be able to payoff my loan by the deadline. I disagreed with that person ' response because their math was incorrect. They said that the reason was due to their policy of not permitting of less than XXXX/month. I stated that provision was not in my agreement, so they were changing my contract. By the end of the call, a manager said they would fix my payment back to the XXXX amount as long as I would make XXXX payment in XXXX for XXXX. I agreed to do that and did it. On XXXX/XXXX/15 I get a call from Citi servicing stating that they can not change my payment to XXXX due to policy and my payment would be XXXX. I asked the lady to please review my repayment agreement for that provision, and I was told that she did not have a copy of this agreement. I am complaining about this change in payment amount. If this was mortgage servicing, the servicer would be getting in trouble for improper billing. Student loan servicing should be held to the same standard. Also, Citi has not sent me an explanation of why payment has changed, the breakdown of the repayment plan I am on with this new payment, or the time period it will take to repay my loan off based on this new payment. Surely this can not be the way a borrower should be treated in this manner. My loans are in good standing ; I am rarely late on payments ; if I am late, it is due to simply forgetting ; I have no outstanding late fees ; and I 've paid off a lot of my loans that I have had. Why is Citi treating me like garbage. My trust with them has gone completely away, and I am unsure if their billing statements have been accurate this entire time.
