Who called from 2093675000

Called my home phone repeatedly with just beeping. Called number back. Blue cross blue shield unused extension

Fax beeps

Some makakas are calling my fax line from 209-367-5000 and 916-350-6001.
How could those animals from blue cross or blue shield be stopped?

How these blue [***] are allowed to annoy people without any fear or accountability?

17 fax tones to a voice line in one day.  How can I make it stop?

I just updated my easy pay information with Blue Shield via Fax and missed a field that the form needed. I kept getting calls from this and another Blue Shield fax. It appears that they fax back to inform the subscriber of an error with the form.
