Telemarketers qualify for me especially 281-203-0420 which is a Yellow Pages scam that calls several times a day
I looked them up
here and it said they sometimes say they just want you to verify your Yellow Pages listing, then when you say "Yes," they use the recording of your voice to make it sound like you agreed to suscribe to their $59.99 a month listing, then they threaten to take it to collections if you don't pay.
