When you have a device like a magic jack, and you rig it up the way you want, you can pick any phone number you want to show up on someone else's caller ID. So if the company is located in pacific time in this country, they can very well have a riverhead phone number exchange if they want to. doesn't mean they are physically in riverhead ny. its a scam. the same people make the same service of calls saying they are LIPA shut off service and will shut off their power if $500++ isn't paid immediately over the phone with a credit card. same people. block the number if you must through your provider or hang up, please make police report because this is getting crazy.
