I am having issues with removing the ruledline between my chapter number and chapter heading. I wanted to add some space between the TOC heading and the actual content list. Here is my MWE. Please help me. I have been battling this issue since the past week with little success.

\tocname, are you? And perhas you want to have a look at this question. BTW, I like your attempt to provide some code, but it would be much better if it started with\documentclassand had some minimal content ending with\end{document}. In particular, the answer to your question may depend on the document class you are using. – Oct 01 '18 at 02:22\begin{document} .... \end{document}which generates some table of contents and illustrates the issue. – Oct 01 '18 at 02:42
