The call comes from somewhere in the US. The National Do Not Call List doesn't apply to the US. The secret is not to answer calls. My telephone company told me there are 'autodialers' out there. Obviously this is one of them. In time, they'll stop calling, but I too don't like being disturbed over this sort of thing.
I have been receiving between 3-5 calls a day from this stupid number. I called it back only to reach "hannah" go along with it.. you will reach a live person. They just end up hanging up on you. They don't listen past hello.
I receive calls from this number at my phone at work daily, sometimes few times a day, during the last 2 weeks with the automated message from "Hannah". I am in Ontario, Canada.
Don't know how to stop it. Quite destructive.
