Scammer number: 205-850-3482
Any other scammer information: From the voicemail: “This call aims to notify you that your back tax debt has been classified as non-collectable so you won’t need to pay it back. This is an aspect of the new federal economic recovery program that’s been in the news. Therefore before you file or make any arrangements to settle your tax debt, kindly call us back at the same number.”
Phone lookup shows it is a Twilio number.
Twilio responded to my report of the number and they say it’s a Vonage/Nexmo-Syabase 365 number.
