Hasn't been denied though yet has it? even andy didn't deny it in the DMs
In the DMs I've seen he hasn't denied contacting the club to basically say that Winstanley is trouble-causing arsehole who they should do something about but there's no mention of any PI. Benji himself is alleging it and Jazz seems to only be confirming that he had heard about. None of that means it's a fact and definitely happened. In fact given the track record of the person involved I'm inclined to believe it's utter crap from a well-known dramatist.
I would like Andy C to address it though.
