Yes I do understand - One of my internet connections at home is with Xnet. I was happy with the performance until the torrent plan was implemented since I browse sometimes after midnight.
They can`t keep everyone happy, unfortunately. They make business decisions based on numbers. I guess they made some research and found that Not many people stay up after midnight to use the internet. There will always be exceptions of course. Maybe they could shrink that free period a little, like mentioned before. It would still do the job it`s meant to.
