This is a scam of the lowest order. The caller will act as if he/she is fumbling around with his/her headset, then ask if you can hear them now. Do NOT under any circumstance say the word "yes" or anything like it. As one poster said, it's someone selling cruises but this is worse because the people making the call are recording it, and they'll doctor the recording to have you saying "yes" in response to the question of whether you want in on the cruise, even if you hang up on them before then. Then they start sending you the bill. This is nationwide and a lot of people have been ripped off.
Low life form calling. Did not answer. I no longer answer any calls. Why should I? If it is a real person that genuinely needs to speak with me, they will leave a message. If the message is unwanted garbage. I delete the message and block the number. The Do Not Call list is a joke, the FCC is worthless gov agency that has done nothing to stop abusive spam, fraud, phishing. Fake identity, phoney numbers, scams, and they should be shut down. Perhaps reopened under better more technological capability. Phone companies with their boasting of high tech features are unwilling to make any effort to address the basic harassment of telemarketing scum. That's why I no longer answer ANY unidentifiable calls.
