Someone called from this number and didn't leave a message. I tried to call back and it went straight to VM, the message was in Russian maybe, and then said press 2 for English. I pressed 2, then it asked for my card number. Nope!
Answered call. Man with an accent said he was an engineer with Windows and someone was trying to hack our computer. He asked if I was in front of my computer at the moment. I told him no and I would need to call him back and asked for a number to reach him at. He muttered omg and hung up on me. My searches indicate this number supposedly belongs to Global Crossing, which according to Wiki, was acquired by Level 3 Communications in October 3, 2011. It feels like a big ole scam.
