They tried this with me this week. First they called my elderly father-in-law at his home and asked for me by my maiden name, plus asked for three other unknown people by their name. He was told it was about a collection account for American Express or City Bank. I called their number from my phone and their rep., "Gopal" began telling me that I owed an old Southwestern Bell bill from 2000 but could not provide any verification that I owed this bill. It was really odd since I had MCI service during the time in question.
