Just received my third call from this number. I do the survey, then answer "No" to the trip. Recorded voice then says, "Sorry to have bothered you," and disconnects.
Received a call on my cell from (210) 319-5064 on 4/11/2016 at 3:45 PM. Caller not in my contacts so I didn't answer, and I have blocked them from calling again.
It is unfortunate that people think nothing is wrong with violating our privacy, but until there are laws passed that actually provide real punishment to those who make these calls, we will just have to put up with the inconvenience of having to block them ourselves.
