I did the same thing years ago where I worked. The IT dept. disconnected my telephone later that night, after work, and I had to call them next day and explain why I’d called that number. I was a 50 year old grandmother by then so it didn’t take long. I can’t imagine what a guy would have had to say to get their phone reconnected.
That was me, don’t really fit the stereotypical person to call that type of number. They didn’t disconnect my phone, but I went and grabbed our IT manager and self-disclosed. Thought he was going to pass out, he laughed so hard.
