Nelnet sent me a letter asking for payments on the loan of someone I do not know, but who shares my last name and first initial. I have recently gotten many debt collection phone calls and another letter for this individual. So, I called Nelnet and asked for my phone number and address to be deleted from the system, and I was told that was being done. In addition, I asked for contact information for the service that gave my phone number to Nelnet and that matched my phone number with my address. I want to call the service so I can stop it from giving out my information and so stop the harassment. Nelnet refused to give me any information about the service.
