the Sallie Mae web site is difficult to make online payments. The loan account numbers do not all show up in loan summary. I have to click on other loans to have them appear. Then the previous loans disappear. This site is difficult for me, and I have had too may years of experience with student loans. My last month payment was reversed, I did n't reverse it, the bank did n't and Sallie Mae did n't either. But, I paid a late fee because of it!! HELP!!! I fear that when my son graduates in XXXX, the site will be difficult for him and could result in loan default. PLEASE help fix this mess. I dislike having to work with these private loan companies. Then, trying to get an answer from customer service is exhausting. I asked to speak to a supervisor and was put on hold for 30 minutes. I HUNG UP! I have better things to do with my time.
