The spammer are out in full force today. I am having trouble keeping up with turning in fake phone calls since they are coming so fast. This one was to enroll me in health insurance.
Opting out just confirms that you have a working phone number.
Here is an idea. Get a live person and ask them to hold for a moment. Put the phone down and listen to them continue to say "hello? Hello? about 20 times until they hang up. Time is money to them
This is the first time I think I've seen this one show up. Since it was an out-of-state number, I didn't answer it. It went to voice mail but had already started its automated speech so the only part that was recorded was "Thank you." Caller ID said Health Insurance.
