2 messages left within a couple hours and sounded so robotic. Exact same message. Said "This message is from Canada Revenue Agency. The very second you receive this message, we request you to return our phone call as soon as possible. The issue at hand is extremely time sensitive. I am office Hannah Gray from Canada Revenue Agency and the hotline to my position is 289 855 2841. I repeat it's 289 855 2841. Don't disregard this message and do return the call. Goodbye and take care."

I called them back and gave them a mouth full.

They are Fake CRA. They were able to repeat after me text in Hindu with aspirates without any mispronounciations. I called the receiver Bhûsrikê and he repeated it.

Complain to Fibernetics.  This guy is running a scam. Complain to police as well.
