Admins can block people whenever they wanted, even bad reasons, or even no reasons at all. If you believe the admin should lose their rights, the community could make a vote whether or not the admin should be demoted. If more than half of the community agrees, then send this to staff via Special:Contact/general and include the link to the vote as proof.

Sannse created a well-written blog of why staff don't remove bad admins and how to work with an admin dispute

Also, if the admin doesn't want to respond to your issue, or says no, you will have to move on. I know it's frustrating, but it's considered a harassment.
