Yes, it is Global Credit & Collections Corp calling under various local numbers (if you live in the St. Louis area). I answered my phone 9/14/09 and received an automated message asking me to immediately call 866-577-5827. They did not say in the message who they were or who they were looking for. I called the 866# and found out the name of the company.
They claimed to be from the Acclaimed Prostitute Department (which isn't a real thing) and asked for Nikki T. (Thomas, maybe?) Saying that she was a person of interest and to call back. I didn't, as I'm positive it was a scam to get money or something of the sort.
