When you really, really, really need some help or guidance, you may get a shepherding call once. They may be fairly sincere in seeming like they want to help. However, if the problem persists, most will throw up their hands as if they've done all they can do and walk away.
However, if you have violated the most minute JW letter of the law, you will be pounced on by a pitbull who will not let go until the smallest detail of your infraction is uncovered and exposed.
Speaking from personal experience. I am sympathetic to a point with them as they are run ragged by the organization and can simply do so much to the point of exhaustion. Whenever the topic of "elders" is addressed in a publication or at the meeting, though, the emphasis is always placed on "shepherding the flock." There is very little of that, but a lot of policing.
