Just received a call from 289-512-0307. Unfortunately I wasn't home. It was so garbled at the beginning I only got "CRA Revenue Canada", then he continued on with the spiel and yes it was a heavy accent. Unbelievable these idiots are so bold. It only bothered me because it upset my 74 year old mom. I told her not to worry, it was just another con by useless individuals with nothing to contribute to society. I never respond the first time to anything anyway.  Apparently these [***] get belligerent too. If someone is contacting my home and interrupting whatever I'm doing, they better be polite!! .
