I am so sick of these calls... I stop what I'm doing, check the ID and of course, they never leave a message. I know it's probably automatic dialing until some poor fool picks up. I used to keep a whistle by the phone for heavy breathers, maybe these [***] need a whistle to drop from calling me!
I do not answer if the number is not known to me. Sounds like a scam. I call them piss ants. You don't get anything for free. I'm on the do not call registry which must be a joke. Another tax milk.
