It's a survey by a company called Protocol for BMO Bank of Montreal. They will call until you do the survey.

Called me today. I miss this call.
It leave message from answer-machine of BMO Bank of Montreal...???
Let's say, I don't bay it ;-)
BTW, I'v got more calls from BMO this week:
(855) 456-3102 - I'm not sure witch language they'v speak...
correctly was prononced just " Bank of Montreal" , probably recorded :-)
And
(877) 666-6339 - better French than English...
I still not bay it ;-)

This number called several times and leave no message.  When I answer, they hang-up, impossible to call them back...... Annoying, it must stop!
