We got a call from this number today at 10:07 am and didn't answer. The caller ID was LYNFIELD PLUMB. No voicemail message was left. When I called back (our number is hidden by default on outgoing messages) I heard a recording which said "Thanks for calling. The survey you were called for has now finished. If you would like to be removed from our list for future calls, please press 9." I have heard this recording when calling back other numbers. They disguise themselves as a survey to circumvent the law. This number will be added to our call blocker.
