I am the co- signer for my son XXXX XXXX private student loans. Over the course of time I sent money order payments in to pay off the loans I co-signed. I specified with the payments that they be applied to the loans I co-signed and to the one with the highest interest rate first. Some of the monies I sent was applied to other student loans that my son had which were Federal Loans and I did not co-sign. I did not keep good records of the payments I made and my son lost his job and stopped making loan payments. I have called XXXX XXXX and Navient numerous times to try to go over the payments so they could apply them properly. I have spent hours on hold waiting to get to the right person and then promised that they would get the information together and call me back but they never do. They have since sent the dept to a collection agency and they are calling me for payment. I am pretty sure that I have paid more than I co-signed for and I need them to give me the loan history so that I can tell them which payments I made that were not applied to the loans I co-signed. They have also reported to the credit agencies that I am delinquent and ruined my credit. I have a small business and rely heavily on my good credit standing to buy merchandise.
