I received a computer-generated voicemail message without any record of having received a phone call (slydial?).
The voicemail directed me to login to "my account" at www(dot)verizon23(dot)com to claim a
$23 credit. I did not visit the website as I suspected a phishing scam/fake website.
I would like to know whether there is a way to block people/computers from sending direct to
voice mail messages.
