This number keeps calling my parents home, so I blocked my number and called back. Man answers and I just told him that I was CRA and he is a !(#(*%(*# - then he hung up.
I did the same thing again and called back - didn't answer.
3rd time - he answers and says I have the wrong number - said, what's wrong, you don't like people calling your number repeatedly bothering you? He hung up.
It's easy to hide behind a fake phone number - just block your numbers and call the number back - bog these idiots down with the same c**p they lay on everyone else!
