I called the number back and got a recorded voice that said "Thanks for Calling! The survey you were called for is now finished."
Then it said to "press 9" to be removed from the list for future calls.
Appreciate that other's have posted. When I get a call, even a local call (like this number) that I don't know, I don't answer. If they don't leave a message it is highly likely to be spam/phishing call. Blocked.
