This number belongs to the Kinsmen Sports Centre.  I believe it's the public phone line.

This number called me when I was out, but it is actually an invalid phone number. Since it is invalid, how it could dial my phone number?

It is very clear that someone is doing wired thing to me, and I considered it as harassing phone call.
