If you have registered to a Company Presentation and can't attend you have to unsign within 24 hours prior to the event. This is done at sasse.se - the same place where you signed up. If you do not unsign and don't show up to the presentation a penalty fee of 200 SEK will be charged. You CAN'T unsign by contacting the Business Committee. This has to be done at the SASSE events page.
