I called back and it instantly went to a recording asking if I wanted my # placed on a do not call list. Definitely don't enter your number, I'm sure that will be rewarded with even more calls.
This number called on 3/31/2017 @ 5:02 PM Eastern time. Just now getting around to log it. I have gotten these calls from "Consumer Services" below, which I know is total BS. One time, just for kicks, I got one of them on the phone and kept having him repeat himself, because I said we had a bad connection and I could barely hear him. Most of the time, I don't answer, and when I do, I hang up.
This number called me several times. Once I determined it was spam I answered and threatened to remove the caller's digits and force feed them to their gerbil. I have not received another call.
