Fraudulent Voicemail

I received this voicemail yesterday.

"Hi this voicemail is from Comcast Xfinity our billing system indicates that you're 50% discount on monthly bill is being terminated today this action is final unless we receive your immediate response please call back on the number showing on your caller ID to maintain your current rate thank you…”

from this number in Ohio, [Edited: "Malicious Phone Number"]

Please shut them down. I'm sure many of your customers, particularly older ones are falling for it.

Thank you.
