Who called from 4255580156

This number keeps ringing my telephone all hours of the day & night. There is no recorded message or person on the other line; there is simply a series of beeps then a hang-up. I am not getting sleep throughout the night, and it makes watching television a drag.

I received 5 calls from this number between 9pm and 6am, with the beeps just like above.

I traced the lat/long of this Verizon landline number to a building on the Microsoft campus in Redmond, WA. Think they care?
