Who called from 4036543211

Called and hung up on voicemail. No message

They call often and usually never speak when I answer. Today they did respond and they were claiming to be from Safety Alarm Calgary. They knew my address although I am not signed up with them nor am I in the yellow pages!

I upgraded my phone security by blocking them :-)

Hung up on answering machine. 654 not a Calgary number?
