Got a call from this number on Feb 16. Did not answer. Looked suspicious.
Also got another call from 416-000-7931 today. Did not answer.
I have the same question as you, suspicious.
Have gotten this call a few times, finally just went through the motions. After two minutes I was put through to an actual person. They were VERY evasive as to how they got my number, and they REALLY wanted my name. I asked how they got my number/which company they were, again, VERY evasive. I asked them to never call me again, and the girl said that she would put me on her 'Do-not-call' list.
We'll see! (I'm from Alberta, a few people from work have gotten the same call. I'm on Rogers.)
