It IS a Time Warner Cable automated survey. Of course, you wouldn't know that from the "Tom Campbell" name (which also showed up on my phone) or the random-[***] 213 area code, but if you had any interaction with TWC within usually a 24 hour period, you could get a follow-up survey call from this...or any other number, for that matter.
I got calls from "unknown caller" and from Tom Campbell after calling Time Warner customer service. I didn't pick up. From reading the above, now I know.
This guy just called me and said I was selected for a grant from the govt. I told him to stop calling and he just kept saying why and would laugh. His English is about as good as a 5 year old and I don't have time warner so no survey for me.
