Keep getting calls from National Prinicpal Group regarding a bill I supposedly owe. They ‘ve also harassed my parents and my ex in-laws!? Finally spoke with someone and told them I never had a contract ( or heard of the company they said I was in violation of ) with or had an account at the bank they said I drew the loan on ( again, never even heard of the bank ). Told the woman calling to send it validation of the debt because I was debating it. Said she was sending time sensitive information that I needed to respond to, but did n’t. Instead, 6 days later, I get a demand for payment, but still no debt validation. I do n’t owe this debt and they keep harassing me and everyone I know but using different phone numbers. You block one and the spawn another.
