No one else reading this page can ''take serious action against '' anything on your behalf. Controlling your nuisance callers is not my job, not another reader's job, and not the site Admin's job.
Ignore official-sounding gibberish spouting from this number. It's a magicJack number. The person using this number probably bought a magicJack device from some electronics store knowing that it can be plugged into the Internet, be assigned a no-cost US-based phone number for 6 months, and can be used from anywhere in the world there is Internet service while being nearly impossible to trace back. He probably scams part-time from his mother's basement whenever he needs extra spending money.
IGNORE calls from this number. Do NOT call back. Do NOT answer them. Try to AVOID letting them go to your voice mail.
