I let answering machine take it but did hear boiler room activity in the back ground. I let these calls run-out then
erase/delete. It's obvious that the carriers make money with these clowns.
If we as regular victims of obnoxious telemarketing went to all that trouble you described for every scam phone call we could literally spend 40 hours a week doing it. You are giving out our info for profit. You grow up. Get a job that actually contributes to society rather than the one you have; annoying society.
