Apple Silicon Mac Support

I cannot find any links that show me where to get help for the Apple Silicon Mac program. This entire experience has been a nightmare. Now the device will no longer let me log in and I can't seem to put it into a mode where it will reinstall from scratch. I wish I had saved our money and never had any part of this program. This hardware is not mature enough even for alpha and beta testing of anything. Who do I contact? Where do I contact them?
