Manager not responding over calls and messages for early release

Hi all, I asked my team for early release, scrum master says they are good to release me post oct7th 2024, initially manager agreed to this, and asked me to check with HR and if HR is ok manager will give a supervisor approval. Now that HR is also ok with that, manager is giving reasons saying that senior manager is not agreeing, when asked what will I do in team there is not requirement post oct 7th, they are telling me that i will be moved to a new team. Now when I am trying to reach out manager and senior manager, both are not responding, neither over text not over calls. Please help me out with sound advise and suggestions. Thank you
