I called to make a payment for my student loan finally a real person answered I told her I wanna pay my student loan she asked me if I want to email my receipt I said "yes" she transferred me directly to the automated system and that automated system it never asked me if I wanted to email my confirmation number until now I still never get my confirmation via email. I don't know if my payment went through or not! I keep checking my bank account and did not see the Uheaa transaction. so I'm hoping my payment go through!!!
