"Aloha, you've won a travel promotion....."
These telemarketers call you with an automated recording that lets you press 1 to talk to a real individual.
Press 1, and then you get an answering services who demands your full name and verifies your phone number. They ask if you want to be transfered to the sales department. They however will not identify their company. If you give the screener any problems, like asking "is this offer open to fraud investigators for the local police department?", she'll transfer you to a different number for removal of your phone number from their lists. You'll hear a recording asking you to enter your phone number. The message says they'll send your number to all their clients, and ask them not to call you. However it seems to only be a recording that doesn't actually record the digits that you enter. At the end of the recording when it tells you to enter your phone number, it disconnects immediately.
