Just called TWC and they looked up the number for me.....they confirmed that it is not them but a political survey. My guess it's really a scammer trying different angles to get personal info. I have blocked it....suggest you do same.
They keep calling my phone looking for a guy who had my phone number about 3 years ago.
I think they are bill collectors. I am getting fed up with them because I was able to find the guy
they are looking for easily in about 2 minutes using Google.
They are very annoying and obviously stupid and lazy if the best they can do is call old phone numbers.
