I received a letter from Regional Adjustment Bureau XXXX XXXX XXXX stating that I owed {$7200.00} ( {$4800.00} principal and {$2400.00} interest ) to XXXX XXXX and they were collecting. I have never heard of this company and do not have any unpaid loans. Upon calling to inquire I was told that this was a student loan of my daughter 's that I had cosigned on from XXXX XXXX XXXX University in XXXX where she attended in XXXX. She has not had anyone contact her from this or any other collection agency and is currently making payments on her student loans monthly.RAB Inc told me they did not have to contact her because I was a cosigner of her loan and I was responsible for paying. This is the XXXX I have heard of this issue and it seems shady to me since it was over XXXX years ago and no one has contacted me about it or contacted my daughter. She is paying her loan so this seems like a scam of some sort.
