This number, as well as another number have called me numerous times, with the same "reference" number. They've tried contacting my family members, as well. Refuse to tell me what the "case" is pertaining to and get very belligerent when I tried to ask questions. Ironically, this number is supposedly based out of Wyoming; while the other number, with the same "reference" number is based out of Georgia. Claimed the company name is National Pre Litigation and that they are a law firm. False!!! I checked with the BBB, as well as Georgia yellow pages. No such company is in existence. I honestly, don't owe any debt collectors and my student loans are all in good standing. Funny enough, I'm Pre Law and informed them that they were in violate of the Fair Debt Act. He did not like that. So, be aware!!!
