I think we are miscommunicating. For whatever reason you have reached those limits. Whether it is your doing or not is, sadly, immaterial.
The system has decided that you have breached the Free limits. Technical support is a paid service. So my advice still stands. Or you have to wait until the month times out. But if the rogue device cannot be disconnected then you will be back where you are.
At the bottom of the reference page is a link to contact support. You could try following the option to submit a ticket as a guest.
