On XXXX I was contacted at XXXX I missed the call and called back at XXXX. I was then told that they had an important business matter to discuss with me and they needed me to verify my address. I then told them I would n't give them any of my personal information, they called me and should have that information. They then continued to claim this matter is affect my credit, and if I do n't resolve it there would heavy consequences. This is odd, because I have been building my credit since my bankruptcy and have really been pushing to keep it clean. I then explained that I have no outstanding debts. I then told them I know what your doing ; I will not give any of my information to a thief that is planning on destroying my good name. I then auto rejected their number immediately. I then received XXXX more calls in the following XXXX weeks. I Called and reported this to the local sheriffs office in XXXX Utah on XXXX XXXX 2015. I gave him the number and the spill they told me. He said if anything comes up on my credit to then call him again, and he would give me a case number to fight the charges. I called XXXX XXXX XXXX 2015 at XXXX and told them I know what they are doing, I demanded that they remove my number from their call list. I also told them I reported them to the local sheriffs department and if any charges are placed on my credit by there company IC Systems. I would take action against. He claimed his company is n't fraudulent, and I confirmed that he understood what I said and that the harassing calls would stop he agreed. I then hung up.
