My complaint:
NBC airing a townhall interview with Donald Trump at the same time as the previously scheduled town hall with Joe Biden is outrageous. It undermines a neutral position as it interferes with the original debate time schedule in which Biden is complying. How can you call yourself a serious news channel while so obviously siding with one candidate by airing this interview on all of your channels while Joe Biden is only on ABC. I will no longer watch your evening news.
Suggested solution:
Publicly explain your reasoning.
