A dead line.  I called it back and it is not in service.  A couple minutes before that call i received one from MJR collections  (905) 671-4151)  probably the same company using a different line.

keeps calling my number, no one there.  Calls 2-3 times a day

This caller never answers when I lift up the receiver.Haven't a clue who they are except to say they are a nuisance.

Received call from this number, male voice asked how I was and then stated a company name, which I could not understand because of the accent. I said I was fine but did not want to talk to him and just hung up

got calls 3 times today with this number. Each time I answer, this is hanging up ...

I ignored the call.  No message left.
