Yelling at these telemarketers to "stop calling" on this forum is a waste of time. What you have to do, what we all have to do, is report them each and every time they call us to www.donotcall.gov. Sure, you can say 'they' aren't doing anything, but they cannot do anything unless and until they know the number that these scammers are calling from. They are trying to shut them down but they need our help. Report them!
These are all scam calls from spoofed numbers. Complaining to the government isn't going to stop them either. They intend to steal your identity and steal your money, so illegally calling you from a faked number is the least of their crimes. I block them when they come in so I have a little peace until they change to a different spoofed number. This credit card scam is the most persistent of course -- they're probably located off shore.
