I got a call with suspect voice and tone. He was telling he was a Government inspector and wanted to do an audit, He told his name was Robert something and gave this number. Voice was like telemarketers but it was money threatening. I hung up.
Called that number later and he did not pick up but called in minutes and he forgot if he was talking to me 5 min ago. So I hung aup

The person spoke with a heavy Indian/Pakistani accent, elementary grammar, very hard to understand, Said he was calling from the Canada Revenue Agency, and that there was some kind of problem with my taxes... Did I want to know more, in which case he apparently needed more information to identity me... I thanked him and said in that case I would contact the CRA directly if necessary...
