I received a phone call last week on XX/XX/XXXX and was told the company was Global Client Solutions. When I called the number back ( XXXX ), I got a recording that sounded as if they were saying " XXXX '' or something of that nature. I left my name and number, but never got a call back. Today, XXXX XXXX, I received a call from XXXX and XXXX. I called XXXX and was told the company they were representing was Global Solutions. They said I had borrowed money from XXXX XXXX, which I have never heard of and when I asked for more information they said I made a loan XX/XX/2011 and that they would settle it for {$430.00}. I told them I had never heard of XXXX XXXX and unless they could send me written confirmation that I had borrowed money and never paid it back, then I was not paying anybody anything. At this point, they hung up and would n't give me any more information. If I owe somebody some money they should be willing to give me documentation of the debt and prove I have never repaid it. The number that called me today ( XXXX ) called my home and also left a message with a friend of mine and I have no idea how they got that number. The number XXXX also left a message with my sister and I have no idea how they got her number. How can I make these people stop calling me if they wo n't give me any information to prove I owe money?
