Cannot delete voice channel

There's this voicechannel that has been in our discord for over a month and we have not been able to delete it. We have tried everything. everything, yet this channel has not gone away.

We have nightmares about this voicechannel, and I think some of our staff has quit because of it. We need help deleting it. Please, stop this madness.

Here's a gif:
