I asked a question looking for a epsilon-delta proof for the Chain Rule of Limits, however the question was marked as a duplicate for a similar question but it does not provide the proof I was looking for. In fact someone had already mentioned before that it wasn't really a duplicate. I would like to get this question reopened. Is there an appeal or request I can make?

The link to the question is below: How to Prove the Chain Rule for Limits Using a $\varepsilon-\delta$ Argument?
