We got a call from this number today at 11:37 am and didn't answer. The caller ID was CAMBRIDGE MA. No voicemail message was left. When I called back (our number is hidden by default on outgoing calls) I heard a message which said "Thanks for calling. The survey you were called for has now finished." This is another telemarketer or scam disguised as a survey to circumvent the laws pertaining to the do not call registry. The number will be added to our call blocker. I highly recommend such a device to avoid these nuisances.
I answered even though I didn't recognize the number because I was expecting a call. The caller said he was Josh from customer service(though he didn't give a business name) and that I had won a vacation. I said no thanks and hung up. I'm so sick of these bs calls.
