You can't battle them until after they've completed their tunnel, and that won't happen until after you conquer the Elite Four. If you've already done that and can't battle them, then you probably cheated and will need to reset the game if you want to be able to proceed in the story and/or connect with Ruby, Sapphire, and Emerald.
you dont you battle them at the rocket warehouse on 5 island
to get the ruby in mt ember, you must have delivered the meteor to the man in 2 island's game corner and found lostelle. then when bill leaves, talk to celio. he will ask you to retreive a ruby on one island. now go to mount ember. you should see two team rocket guys. you will overhear them talking and you will also hear one of the passwords for the rocket warehouse on 5 island. battle them and they will go away. then go in the cave. the only monster in there is slugma. keep going until you find a room with braille in glass cases.go down the ladder on the bottom right corner and get the ruby
