Companies keep calling - AMEX called me this morning at XXXX in the morning. I have told them to quit calling me because they are seeking a person named XXXX XXXX ( unsure of spelling ) and I keep telling them my name is XXXX XXXX and I do not know how this person is. I have my number on a DO NOT CALL REGISTRY and AMEX called me at XXXX this morning and woke me up. I asked multiple times to for them to identify themselves and he kept asking me for this XXXX XXXX and would not identify the company name. I had the caller on my caller ID so I called it back to get the identification of the company and found it was American Express. I gave them instruction never to call my number again - but have given instructions in the past. I do not want people calling me at XXXX in the morning. I need help and if I need to get an attorney to sue AMEX for this harassment then I need your direction on what steps I need to take. I could understand if it was me with the debt issue, but I have no credit issues with anyone. I want this harassment to stop.
