Who called from 6477991947

Calls keep coming to our offices from this number. Most times there's no sound or anything. One time an automated message started playing saying that the "CRA (Canada Revenue Agency) needs to hear from you!" but they don't say a name. This is obviously an automated scam bot.

I get more 10 calls a day from this # and is so annoying.

Have you considered obtaining a call blocker?
If not, what is your "annoyance threshold" before doing so?

They just called me and when I answered it they hang up.
