All your information belongs to us
Thinking of applying for a student loan? There’s no shame in that, seeing as how a college degree can cost a small fortune (at least in the US). However, in this day and age, if you hand over your personal information to anybody, even a student loan servicer, get ready to receive targeted ads for your troubles.
According to the OP, saving somebody’s personal information, like their bank account numbers, is a no-no. But if the servicer can make a few dollars on the side by selling your personal info to ad companies, ethics be darned. Money is money, and there’s no question that they want to profit from your misery.
