These scumbags are spoofing Caller ID, using a VOIP robo dial program.
Sometimes, the spoofed phone numbers are not valid.
Sometimes, the spoofed phone numbers are legitimate. When this happens, the real owners of the spoofed numbers become victimized by hundreds of angry people like us.
Being on the DNC list doesn't help.
Having an unlisted number doesn't help.
A computer is doing all of the work.
Ok. So, as others have said, this is a scam, and they call from multiple numbers. Here's the different numbers they've called me from: this number(469)270-9011 Allen, TX, (216)322-8377 Cleveland, OH, (205)383-3085 Birmingham, AL,(616)227-4260 Ada, MI,(205)337-0372 again from Birmingham, AL. I've been getting these calls since November 2015. I've never answered any of them. But I've looked them all up on this web site and everyone says the same thing: all these numbers are the same people, with the same scam, from different phone numbers. DO NOT ANSWER, do not give your private credit card info away.
