Internet light on modem is red

Hi since receiving my Tele 2 internet box and some other information with details on installation, I was given a time and date on which it was activated for my use. Over two hours past that time it has not been activated and any time I try to establish the dsl connection from my PC I receive an error code the media access page. The money also hasn’t been taken out of my account I’m thinking mainly this is the reason?? Any help appreciated!!
