Who called from 2048001701

they do not  answer when I answer my phone.

FRAUD;  I just had an agent from the CRA on the line. I had her listening to the recorded voice message and she told me the call wasn't from them ; it's a scam. No one will take a legal action against you, and CRA would never leave that kind of recorded message. Do not answer, do not call back.

just got a message on my voice mail from them, sounded pretty sketchy

Call calmed to be the CRA.

This is a scam they claim to be from CRA  requesting financial info. When I called back a magic jack message stated that the caller was not available
