Hello Ziochioviel65
Good day and welcome to the SBB Community.
This website is not made to communicate your frustration towards SBB. We are a customer support page run by volunteering travel experts, reading your lines in their spare time. If you want to transmit your feedback to SBB, please use the appropriate form made for that purpose:
https://www.sbb.ch/en/help-and-contact/customer-service/praise-comments/reklamation.html
The line is closed due to maintenance work. And this has been planned and announced well in advance. It is not the first weekend where the line is closed. There has been a media release as well:

SBB hires local bus companies or Postauto to operate rail replacement buses. They plan and organise the buses independently. Your feedback to SBB helps to improve this service.
And, yes, even if you understandingly are frustrated, a hello or greeting is still appreciated. Remember, your lines are read by another human who is neither responsible for the unsatisfied service.
Kind regards,
Roland
