LEGIT call from LG within an hour of my calling them for a support issue. When you call in the IVR menu asks if you wish to do a survey after your call to review your interaction. If you say yes, you get this automated callback anywhere from a few minutes to a few hours later.
You are correct, but caller ID showed "Blocked" and the number, so I didn't answer. If they really wanted my opinion, they should have let me know who was calling.
