This is only ONE of the MANY numbers that call me in the middle of the night.

This has been happening (almost every night) since I entered my phone number into the healthcare.gov computer system.

Strange calls....ALL hours of the night!  
NO one is there.
When my VM catches it, I get crackling for 10-20 minutes before it hangs up.

The calls come from numbers ALL over the USA.

Is this some government computer system calling us?
.....harassing us????
.....waking us up at all hours of the night???
