A company by the name of National Principal Group contact myself and several of my family member leaving a threatening recorded voice message. I spoke to XXXX of their " representatives '' all of which claimed I owed a several hundred dollar balance on a pay day loan, which I had never taken out. Each time I contacted their offices to request emailed documentation of the alleged debt, I was assured that it would be sent. Finally, after XXXX attempts to recieve this email, they sent a generic password protected email. I called back to question how to open the attachments, and the office manager hung up on me. I called back XXXX more times, and was hung up on XXXX times. I believe this to be a fraudulent company.
