This company only wants to suck you for all of the money you can possible provide them.

I use teamviewer frequently and pay for it, and I use it across multiple devices. I have a habit of signing certain devices on and off so as not to run out of available spaces on my license, but the people who run teamviewer think that I should pay more since I have so many different devices to use for some reason. I cost them NO extra money, yet they call my parents (I do not know how they got their number -- I am 39) to tell them what...? That they need to pay up if we are going to have so many devices on throughout the year? F*ck that and f*ck them.
