I'm using Google Voice with my mobile phone and this is the text they left on my voicemail. I'm sure it was a robocall because of the sound of the voice generated.
Text from voice mail:
"Your Google listing. Press 1 to speak to an authorized representative to verify your listing. Press 7 to be removed from this listing."
keep receiving vm saying to press 7 to be removed. attempted to call number back however recording says number has been disconnected even though i continue to receive calls daily from the number.
