Type of Scam: IRS Scam
Comment left on the main site:
A person named Nicky Johnson called our number when we were out and said we were in trouble with the Canadian Revenue Agency (CRA). We rang back and spoke to a David (? didn't get the last name as it was a foreign voice and English not too good. Said he would deal with it and said we could be sued. When I queried and pushed further (as I know I don't owe CRA anything) he hung up. This number is definitely one to watch and ignore.
