I am getting tons of these calls as well AND "the IRS last chance calls." I'd like to report them to the police as harassment but I doubt they'd do anything. I saw one of the TV hosts on FoxNews who said she was getting them. Best thing is not to answer.
Receive call 4-5 times a day for past week - caller id says Canton Ohio. Today I picked up phone, no one was there so I put phone down on table. Hopefully costs them long distance charges!
