Sally Mae No statments were ever sent in 10 years and now they are saying I owe them money. Wilkes-Barre Pennsylvania

 I started recieving emails a few weeks ago from Sally Mae, stating my statment was available with details of payment that needs to be paid.  I email them back a few times saying I paid this loan off and I dont owe anything.

They finally emailed and I was able to get the phone number to call them. I explained that my loan was paid off and I didnt owe anything more. I explained that to the lady and all she said was I understand but . I told her no you dont understand. I owe you nothing. Why would someone make a payment of over 6000 dollars and leave a balance of 214.00. ? she said I understand...I said no you dont let me talk to a manger.

after 55 mins on hold I finally got a manger who tried to explain to me that since I paid so much money in advance that the 214.00 dollar balances has been there for 10 years. and that it is a student loan they dont send out statements each month.  I said who in there right mind would make a payment of over 6000 and leave a balance of 214.00 ?? I asked again for a more higher up manager

put on hold again for 10 mins. Another guy picks up the phone I go thru the whole thing again with him. He says well student loans dont work that way they dont send out statments. He said I dont see any comments were you called in for a pay off.. I then asked , then how did I come up with $6,661.54 ? Did I just pull that out of the air..No , I got that number from your people to pay off the loan. I told them they screwed up and the person who did that didnt put in the comments and didnt add it right.  I also said asked how in the world is it only 78.00 of interest for 10 years ? I mean if it is accrued monthly.. then i should owe over 10 thound dollars. ? He couldnt explain that.

I refuse to pay it and will consult a lawyer.
