PSDI sounded legit, so i signed up for a few classes through the mail. Before I had a chance to agree to anything, I received two boxes in the mail containing school supplies and books, with a bill. I had already given them my bank information so I could receive financial aid, and they withdrew over $600 from my account, thus causing me to have overdrafts. The next month I received another bill for double that. And now several years later, I still receive bills stating that it's been turned over to collections.
I went through the same thing with them about 6 years ago. I still get collection from them after I paid all of the money that they wanted for me. It's ridiculous!
