Hey there, not sure what you mean by contacting support not working. But you're only able to appeal for server suspensions via a support ticket. If you've created a ticket in the past and it was denied, unfortunately, that decision is final.
If you haven't been able to submit a ticket you can email support@minehut.com or visit https://minehut.zendesk.com/hc/en-us/requests/new
Thank you
