School is XXXX in XXXX, NC. Simm Associates, a collection agency, left several voice messages and then sent a letter informing me they were collecting for a delinquent student loan, for which I am the cosigner, with XXXX. This loan is being serviced by XXXX. After contacting XXXX, I was told the loan was NOT delinquent and since the student not graduated yet, it is impossible for this loan to be declared deliquent. The agent at XXXX was very helpful. When I contacted Simm Associates, the collection agency, at the number listed on the letter they sent, I was asked for identifying information such as my date of birth. I declined to provide any personal information and offered the account number from the letter. The agent refused to continue the call unless I provided this personal information, and which point I ended the call.
