internet survey company

This is an internet survey company...you can opt out, by pressing 3..you enter you phone number, and you will be removed from there calling list..

Recording said, "Thank you for taking our internet survey."  We didn't take any survey.  We started to get a lot of messages recently.  Started with a whole bunch of educational institutions calling for my husband thanking him for his interest, he didn't sign up for anything.  He works and wasn't searching or responding to anything on the internet.

I don't want this kind of calls. Thank you.

How can I stop those calling?
