Why is Bell getting worse?

We are paying for bell, have been on the same plan for years. I used to be able to download games, not in the last year. The whole internet basically is disabled besides my game download. Nobody else can use it while I'm downloading a game, because it's so slow. It used to never do this. Everyone we complain they say " if it's a problem you should upgrade ". And another thing if the wind blows more than usual we are out of internet. Just rediculus
