If you have given A opportunities to solve the problem for you, and you haven't gotten a reasonable result, you have the right to escalate.
There is always the possibility that A will be unhappy. In that case, you just point out the fact that you are still miserable, and you need to live a better life without switching to another team.
A needs to learn a lesson to do what is right, not just what is easy.
Taking risks is an art. It's like playing poker. People who dare to take risks have advantages:)
In this case, you are only asking for fair treatment.
