<prompt> Human: In managing our finances, I set up everything through Mint, and for student loans, Unbury.me. Ive already been paying extra onto my student loans through Nelnet, but I couldnt find a way to control exactly how much goes where in my monthly payment. I was able to do this pretty easily through FedLoan.gov on my wifes student loan account.I have seven individual loans, ranging from 4.5 to 6.55 APR. Upon further investigation, I saw that routinely, my extra payments were going toward low interest groups and hardly any high interest groups. I struck up a chat and told the servicer that I cant find on the website how to control my auto-debit so I could put my extra payments toward my high interest groups.She said she could push a request to put extra payments toward the higher interest loans.I asked if there was a way to do it myself online.She said its impossible.I asked why.She said, Federal rules.I said, Is that true? Because we were able to do it just fine on my wifes account on FedLoan.She said, I cant speak on behalf of other servicers.I said, Can you direct me to the federal rule that prohibits consumers from controlling where their payments go in grouped loans?She then explained that its part of my promissory note.I said, Im fine with that if its part of my promissory note, but dont lie and tell me its a federal rule when its not.She apologized and clarified what she meant.I guess my question is: Is this normal? Are there any further steps I should take?  <response>: Yes, it is normal for customer service reps to make things up to try and get you off the phone.
