We received a weird voice mail today... introducing himself as Officer Foster (he had a strong accent) telling us that we have to call him back. He gave his phone twice. Also We were not allowed to call our attorney because it will not make things any better...or something like that...the rest was not really understandable...

It's a scam "running around" in Canada and the US.  Fake debt collectors.  This is from the US site but the same thing is going on in Canada.
