I do not answer callers that do not identify themselves or leave a message but I was starting to wonder who this persistent caller was. Thank you for ending my curiosity, but I am now more annoyed. I will try the #1 next time they call.
Got sick of getting calls from this number so I called it back. The recording informed me it was a "consumer entity," which is really annoying, considering I'm on the National DNC Registry!
I pressed "1" to get my number removed, but I also intend to report this telemarketer. The National DNC Registry has an easy fill online form you can submit (and a hefty fine for the telemarketers).
