they called but didn't leave a messdage or talk when i answered

Several calls in recent days, always leaving an annoying 'silent' voicemail -- so, yes, it must be automated.  Will block it now that we know who's pestering us.  THANKS for the info.

My caller I.D. said ONTARIO. When I picked it up there was a message in a very official sounding British accent saying that this was Credit Services and due to new legislation I might be eligible for reduced credit card rates. Press 1 for more info, press 2 to be removed from their list. I pressed 1 and when the guy came on, I said I'd like to have the full name of the company and their street address. He said "Sure! Hang on! Then he hung up on me.No real business would do this.SCAMMER!!!

I blocked this number immediately. Call today but did not leave a message. Could be telemarketers.

A call came in this morning, about 10am NS time. No message left, as I was not at home then.

who is this person

What's suspicious about it?  Does the 6 look like it's planning a crime with the 8?
