Who called from 6477890342

An old lady said ,,,Im phonening from Victoria ,we had view your application for CPP,and she will send me another form to fill in about my financial ,then send back to her,,just wait and see...

when I called this number back it didn't go anywhere
The caller claimed to be from service Canada from Vancouver.

Yes ,I received a letter about Consent for service Canada ,so this is Government phone call,I check ed out phone number just because (647) is Ontario code

Did not pick up.Don`t p.u. when I don`t know who is calling.They did not leave message so can`t be important?
