My loan got sold to this 'company' and they took my loan out of deferment even though I have continuously been a student since before they bought out my loan. I started to received letters with ZERO contact information and then the calls started rolling in. I answered and explained that I was in in-school deferment and if they'd send me the paperwork, I'd get it back to them. I spelled out my email address and they promised that I'd get the email within the hour. I check, no email. I try to call from the number that had called me, out of service. I have this EXACT same interaction FOUR times before an agent finally gave me the website to retrieve the paperwork myself. I get the paperwork completed and back to them within the day. I move on and later check my credit score for other reasons and I see that they reported me as delinquent. I have now emailed and called them multiple times resulting in a run-around every time. I will continue to contact them until I get this resolved. They are now messing with my livelihood because they can't operate a company properly. IF you have any choice, do NOT let your loan end up with this JOKE of a company.
