Keep getting a call from this number, and will not leave a VM, refuse to answer, especially after seeing this

I just called the number and a recording says that they're "The Share Group" and called on behalf of a non-profit that I recently supported.  I hung up once I heard that.

Continue to get a call from this number.  Some times twice daily.  I don't answer because I don't recognize the number.  They never have left a voice mail.

I get calls from this number and also 866-239-6769, which is also the Share Group.  I'm going to the Do Not Call Registry to report them.
