Who called from 2132288112

This is the phone number for government grants (there's a TV and print ads for these grants.)

I have received 9 calls from this number in the past hour. How do I get them to stop. I don't know who it is, when I pick up they hang up.

When I try and call them back, i get a busy tone...they call me everyday around the same time.

This number has called me and when I returned their call by dialing out the number on my call display it just put me on hold for a looooong time, who are they and what do they want????

:S

I am currently waiting for them to pick up...good music, though. They've called me 7 times today and it's only 4 o'clock.
