All the "agents" care about is getting the money for their client. For this, they're willing and apparently able to abort at least one flight, and possibly others, costing people on those flights possibly thousands each with rebookings etc, all for £3k.
I've only has the displeasure of interacting with a bailiff once, when I was a naive student. The guy knocked on the door asking after a previous tenant. We went through for any mail addressed to the guy he was after, and while doing so seemed to revel in explaining how he had the power to barge in by force and arrest me if we wanted. In the moment I was slightly incredulous but nodded along. Was only after the fact I researched to find you're within your rights to turn them away unless they're accompanied by actual police.
Seems like the perfect job for power-tripping sods.
