This company sent me a letter about an alleged debt that they claim they received from their client XXXX XXXX. I do not have an account with XXXX XXXX and when I closed my account with XXXX XXXX I left with no outstanding bill as far as I can recall. I have not had an account with XXXX XXXX since 2013. I have never done business with this company in the past for no reason whatsoever. When I received notification from this company about the alleged debt, I responded by asking for " Validation of Debt ''. This company has yet to provide me with competent information related to this debt however, they still continue to contact on my personal phone and on my office phone. I also suspect that this company is calling me via phone at my employment, using a private number. Each call I have answered they refuse to disclose the nature of their call when asked. They have now resorted to calling me and hanging up on me.
