Airtel — junction box removal

I would like to bring to notice that there is a junction box installed without our notice right on our compound wall. Despite repeated efforts to reach airtel, all is in vain. Need to remove the same on an urgent basis.

There has been so many false promises from airtel with regards to broadband. Initially they said there is feasibility and now they have come up with a new story saying no feasibility.
Need an immediate solution.
