Magazines and bags stuck in a ductwork. help!

[Ali Zantout]

I need help and a solution to get magazines and bags that are 6 feet stuck inside a vent ductwork. One of the rooms at my properties never gets air so when I finally tried to open the vent cover and look inside.. I found magazines and shoved plastic and paper bags inside. the old tenant from the previous landlord I guess did that and I never thought about checking in there to begin with when I realized the air flow was bad. There isn't a claw long enough for that, or is there a vacuum that can help? Last resort I would pay a company to clean the vents... help!
