Getting calls from an automatic voice information processing system and I don't know how to stop this.

Hundreds of calls over the last 2 weeks from 416-780-84xx. First couple times is annoying. Last couple hundred times beyond a joke. How do i stop it. Try calling it back and it is from Actel voice information processing in Toronto. Cant even talktp people to get my number taken off.
