I have been a victim of Identity Theft since I was notified by my XXXX credit card company on XXXX XXXX. I already filed a Fraud Alert through the XXXX Credit Bureaus such as XXXX, XXXX and XXXX. I am constantly monitoring my credit report since then. I also filed a XXXX XXXX Police report on XXXX/XXXX/XXXX in regards to my Identity Theft case and filed a FTC report on XXXX XXXX, XXXX. I noticed the suspect who stole my identity opened several fraudulent accounts under my name without my approval since XXXX XXXX based on my credit report. I contacted several and most of the credit card companies to dispute the fraudulent charges against me. The fraudulent accounts and charges were closed in my favor due to Identity Theft. My credit report was restored back to XXXX points and my life seemed to be normal again since XXXX XXXX. I did NOT see anything suspicious or unusual on my credit report such as fraudulent accounts or fraudulent charges against me. I was happy and no longer living in a stressful life. However on XXXX XXXX, XXXX at approximately XXXX, I received a phone call from a collection agency known as Alpha Recovery Services XXXX. The man on the phone was rude and did not show any concern about my Identity Theft situation. I told him that I have been a victim of Identity Theft since XXXX XXXX, XXXX. He responded " you told me that 4 times already '' in a heartless, ruthless or unprofessional manner. He asked me a series of questions such as my date of birth, social security numbers and where I lived. He told me that my conversation is being recorded. He told me that he will be sending some documents for me to fill out in order to dispute a {$6000.00} fraudulent charges against on XXXX XXXX. The company that he works in behalf is XXXX XXXX XXXX XXXX. The suspect opened this fraudulent account since XXXX XXXX. I asked the man how come I did NOT see this fraudulent account on my credit report. The man refused to give me a clear answer and refused to assist me in a professional manner. My impression from my conversation with him was a threatening and unprofessional manner based on his tone of voice. He wanted me to fill out some forms and return the forms back to him in order to clear the fraudulent charges and fraudulent accounts against me. I XXXX Alpha Recovery Collection Services and XXXX XXXX XXXX XXXX and found out there were some kind of scams involved. As a result, I do n't know if I can trust Alpha Recovery Collect Services or XXXX. My identity has already been stolen since between XXXX XXXX and XXXX XXXX, XXXX ( when my credit card company informed me someone used my personal information to open fraudulent accounts against me ). The man who claimed he works for Alpha Recovery told me that he knows my date of birth and social security numbers. The man insisted that I fill the document forms and return the forms to him as soon as possible in order to clear the fraudulent charges against me. I am still hesitant to fill these forms out based on my research and personal investigation about Alpha Recovery and XXXX XXXX XXXX XXXX because these companies were involved in a scam. How come the fraudulent account did NOT appear on my credit report? How come the man seemed defensive when I asked him this question and he refused to assist me in a professional manner? I have been checking my credit report a lot ever since I became a victim of Identity Theft since XXXX XXXX, XXXX. I did NOT see XXXX or Alpha Recovery on my credit report. This is very suspicious in my opinion.
