This was from CharterOne (a Citizen's Bank affiliate) about a TruFit Student Loan. The account was locked due to many attempts with incorrect password and they wanted to talk to the applicant to find out what was going on. Legit call.
It was company (Capital-something - no, not Capital One) that wanted me to finish my student loan application. I did apply for student loans about a month ago. I don't remember applying to this company specifically, but I couldn't deny it either. This number seems legitimate to me.
