No one answered. Not the first time for "SSI" using different numbers.

Called and left no message. Blocked

Survey Sampling International:
SSI is Survey Sampling International, a survey company and has nothing to do with the SSI program by the Social Security Administration, nor 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.

Husband answered, since they've called multiple times over several days, from different numbers.  Husband asked if the caller was American, they said "No".....then husband said don't call me again, for anything.....ID comes up as SSI

Since the last word in the company name is "International", then that person not being an American is possible.

They call all the time and on Sundays.  Says SSI.  Never a message.  Never answer.

It is a survey company and you can simply go to their web site and opt-out. Listing all the numbers don't mean a thing when you can opt out instead of worrying about what numbers they use.
