Sorry I mixed up the area code in the above message. It's 301-634-6111. I have read they call from various numbers using various methods to frighten their victims. Also, he told me he was calling from the DEA office in Bethesda MD. I also wanted to mention that I read 11 individuals were arrested last year in the Dominican Republic for running this scam. From what I'm seeing, this seemed to lessen the amount of calls but I want everyone to know they are back at it again.
I also wanted to mention that in 2007, my credit card number was stollen and I have no idea how that happened either. They made purchases including expensive camera equipment and some other online purchases I didn't recognize. Since I rarely use that card, the bank voided out all the purchases and changed my card number. All I can think is this scam somehow stemmed from this.
Please, please don't feed into these people. Call your local DEA office or the extortion hotline and report them.
