Who called from 8064102064

I'm getting 5 - 6 calls a day from this number!  What can be done about it?

No message.  Local area code.

Caller id says "SSI"  get repeated calls from this number every week.   Does not leave message.

Survey Sampling International:
SSI is Survey Sampling International, a survey company and had nothing to do with the SSI program by the Social Security Administration, not does it have anything to do with the Administration itself..  Opt out:  https://www.surveysampling.com/contact/
I don’t personally know if the above link will actually take you off their list, but I have been told a couple of times that it does work.

Call multiple times a day, including Sunday mornings and before 9 am.  No one on the line and no message left.  How can I report this harassment?
