Ive recieved calls from this number too, it is linked to another number 646480999, they get very vulgar when you try to question them.  Theyve used names like Andy Anderson and John Obrien..be careful they will call your employer, they called mine over 100 times yesterday and called my cellphone over 20 times.  You can report them to the FTC.

I got a call from this guy and uses phone numbers like 7603925048, 7603925848 etc.  Giving false identification, pretending to be an officer with a illegal or invalid badge number.

This guy called and told me I need to contact him ASAP which I did not, then he called back again and gave me a different number 760-392-5048
