Who called from 3236120121

Checked out #. Seems to be spoof.

I am on many do not call lists. I do not wish to continue to receive calls from this number. How can I be removed from the call list?

Many, if not most of your calls are coming from crooks and scammers.  You want to block the calls.

Also received the "one ring" call on a Sunday morning. After reading everyone's comments, I shall block the whole area code since we don't know anyone in the Los Angeles area.

The area code is in Los Angeles, but the prefix 612 doesn't exist for LA.
