I see double one over the other about 20 degrees

Up close to the eyepieces around the barrels are small screws that you can use to "collaminate" your binocs. The screws aren't meant to be accessed by the owner and most manufacturers cover them up with the material that surrounds the binocs. Of course the binocs in their current state are useless anyhow, so I wouldn't hesitate to peel up the material to look for the screws. If you do it carefully, you can reseat the material anyhow. Then once you locate the small screws, put the binocs on a stand or a table outside. Focus on something far away using one eye. Then using both eyes, you adjust the screw on the other eyepiece while looking through the binocs. Adjust until you get a single image. You can use loctite, or nail polish to "glue" the screw in the final position if it is really loose.
