I have NO idea...well, actually I do. But. -.- It pisses me off. I had to give my info to a person at a cable company to deal with my ISP, had to give it verbally because their stupid app where I could type it in isn't working. I think they listed my info on a dark net site and sold it. Or they did it themselves, which is stupid because they're going to get caught. We reported it to the company already, and they said their fraud team would take action.

So either they did it or someone was listening in, which means we have a thief in our apartment building.
