Who called from 6474774131

They claim to be Canada revenue, when I asked them to prove it to me, they hung up on me. I tried calling back but they blocked my call.

Claimed  to be from CRA and tried to frighten me by accusing me of tax fraud. They're hopping you'll surrender sensitive information. Just hang up on these creeps and report it to police. CRA will notify you by mail if there's an issue. NOT by phone.
