Who called from 6138450728

It's legitimate.
I got that call, too, and called them back.
Verified that it's a political party seeking donations from people who've previously given them contact information.

Yes, it is the LIBERAL PARTY of Canada. You are most likely a member.

Liberal Party of Canada. They are calling their members. I am an up to date one, so they called.

Why do they never leave a message then?! plus they're calling my cell so I can't pick up because It would be long distance!! Stop calling without leaving a message!!

Repeated anoying calls with no message.   Desist.
