>>> "YMAX COMMUNCATIONS CORP" which is based in Florida <<<
... is a wholly-owned subsidiary of the company that sells magicJacks and provides all the magicJack phone numbers. of which this is one. MagicJacks can be plugged in anywhere in the world there is Internet service and call into the US showing the assigned number for their device.
Scammers can get YMAX numbers in many area codes, but 202 seems to be popular because it looks like they are calling from Washington, DC. Most people seem to associate such calls with the federal government even though a large number of private citizens live within the city limits.
MagicJacks work well for honest people who use them, but they also seem to work very well for scammers who want to hide behind a US number that is very hard or impossible to trace, and that can be used in places where the US cannot get a foreign government to cooperate in bringing the scammer to justice under US law.
The same thing happened to me. It is important you call the Federal Trade Commission and report it -- they are the policing agency. Get a case #. I did.
James Jones left a message. Said he called on behalf of the IRS. Spoke with a heavy Indonesian of Filipino accent. Lots of background noise. Said that there was a warrant out for my arrest for tax fraud, and provided a warrant number. Asked me to call him back at 202-241-2083.
This person called me but this time he said he was from Pepco, our electric company, and said that they're going to cut off our power in 30 minutes unless we pay by phone. I paid my bill in full a few days ago. Clearly a worthless attempt at a scam.
