Female caller offered a $100 gift card , a $50 dining card and a package of free samples. She then asked for my name, address and date of birth to send them. Then she said it would cost $1.95 for shipping, and she needed my credit card number, at which point I terminated the call. This call originated in Washington, D.C., at a number which appears to be a switchboard or proxy of some sort. Dialing the number gets something which sounds like a customer service switchboard, but when you request to speak to a representative, it tells you they are all busy and asks you to leave a message. A tone, sounding like a household answering machine, follows.
