I've gotten these phone calls then saw this effective solution to stopping the phone calls from a blog comment to email service@callerhelp.org; it's a do not call service for a small number of clients that call consumers. You give them the caller's number so they can verify it on their list of numbers and your receiving number so they can have it removed from the caller's list.

This # calls every couple of days...today this # came up as "Reliant". Whatever that means!!

Don't bother answering this call....a complete waste of one's time.

Get a real job!
