Your workspace has been restricted, and we're not able to share the specifics of why a workspace is restricted. There is no action on your side that can lift this restriction.

I only paid for the hobby plan, I couldn't post anything and my space was limited, it disappoints me, if you can't explain the reason for the restrictions, give me back the money and I'll find another service

We understand the frustration, and we're sorry we can't share more detail on the restriction. If you'd like to stop your subscription, you can cancel from your workspace billing page. To request a refund, look for the refund option next to your invoice under Billing History on the same page - note that refund eligibility is determined at Railway's sole discretion.
