I received a text message on XX/XX/XXXX from my general manager at my place of employment letting me know someone was trying to get in touch with me and he gave me their information. I called the number and gave them the reference number. I was then transferred to a gentleman claiming to be from XXXX. He had all my information, social, amount I currently have available on my credit cards and so on. He told me I owe money for a credit card I had in XX/XX/XXXX. I asked why I had n't received anything in the mail and he told me they had sent it, the mail service can be unreliable. I said I wanted something in writing from them, to prove they are who they say they are. I mentioned that I had n't seen anything on my XXXX credit report and he said it was because I needed to check my XXXX one. I told him bottom line I did n't feel comfortable settling for XXXX and issuing a credit card payment without any knowledge of who they are. He said he could send me a generic email, that would n't pertain any type of payment information to set up, just general information. I was leaving for work at the time and he did send the email which did n't even contain a letterhead. I google searched the number they had called from, XXXX, and found numerous complaints about threatening and harassing calls. I also bought my experian credit report and found that a company, XXXX ran a credit check on me on XXXX XXXX, which would explain how he had all my information. I searched that company and found a phone number but when I called that company it was a voicemail saying if I left a message someone would return my call in 24hours. I left it at that. Then today, XX/XX/XXXX around XXXX someone claiming to be from XXXX? called my place of employment asking for the address and my name, my employee then gave the phone to me. It was a woman claiming to be from a processing server company who told me they were planning to come to my place of employment within the next hour to serve me with papers that would require a signature, I said that was fine. She then repeatedly asked if I wanted a number so I could call and have the serving of the papers rerouted, I said no, its fine. She asked what time I would be here until and I said I 'll be here all day. It 's now XXXX EDT and no one has shown up. I explained to my general manager what was going on and apologized for the phone call. He told me that when he was contacted yesterday the woman on the phone was telling him they needed to contact me immediately or that was it, I would lose my chance of any resolution. He also said that he was received numerous call from who he assumes is them again today but he was not answered to avoid any further problems.
