Don't ever call back a number you don't know...now they have flagged you as a live number and will call back repeatedly and sell your number to other scammers.
Robotic voicemail about a lawsuit. Intro was cut off. Sounds like the old IRS scam...which I am shocked as I heard FTC worked with Indian authorities to shut dozens of these fraud call centers down. Guess they spring up like weeds. Number blocked now but another is sure to follow.
