Someone at XXXX calls my home XXXX or XXXX times a day for another person claiming they are an investigator and she committed fraud. He even gave me the last XXXX of her social security number. I told him he should not be giving out personal information on this person. He said if I knew her I better tell him. I told him I knew her but this was not her number and stop calling my home. He got very irate and told me this was the number he had on file. I told him to remove it and stop calling here and hung up. He called back XXXX more times threatening to go to her job and what could happen to me. I told him do not call my house a gain and I meant that. He told me this was the number her had on file and he would continue to call. He ever gives his name, just that he is an investigator. Wish I could sue him. I am a XXXX, had a XXXX XXXX in XXXX and do not owe any money he is trying to collect. My XXXX XXXX went up yesterday after the harassment. Can you help?
