Student loan question

[Becca]

I just got a 'truth in lending' disclosure statement for a new student loan. From the same place that services my loans, but with an account number and princ. balance I didn't recognize. I haven't taken out a student loan in 9 years.

I called and the woman that I spoke to said that one of my two existing loans was split at the request of a co-signor (so now I have three loans with them). I had consolidated two loans, one of which had a co-signor, the other didn't. <-- I am not entirely sure if that is accurate, I will need to go back and look.

The payment on the loan that she said had the co-signor is suddenly higher than it would have been before. For example, say I was paying $100/month which apparently covered two loans. Now the split loans have payments of $50 and $75 (again, as examples). The life of the 'co-signor' loan has also been extended.

The woman I spoke with insists that the interest rate has decreased from 4.25% to 4.0%

So if the rate decreased, and the life extended, why did payments go up?

Something just doesn't make sense to me. Am I missing something?
Anyone have any guesses on insight?

I am going to call back later and try to talk to someone who can speak English a little more clearly than this woman could.

I'll also print out some statements and reconcile the balances. And maybe give a WTH call to my parents. But if they have anything to do with it, they would never admit it.

I hate loans. I am so tempted to just pay them off and be done with them. But I also like hoarding cash and it makes me nervous to let the cash go.

No clue, none of my loans had a co-signer. But that does sound weird.
