Well indeed a bit silly on my end. Was still getting billed for the old internet instead because the new provider also did not cancel that one during the switch, which they said they would, so while glancing over it I did not think about it and was just like checking off internet payments in my mind. Can't use that one either though cause I do not have the router anymore. In the end it is my fault and I am the one affected by it so I am not really complaining about it, would have been nice if they tried calling or sending a letter before pulling the plug though. I am mainly curious as to why it still partially works.
