Pokemon HeartGold Misty Problem.

AGGGHHHH.
I Dont know why but i never met the team rocket guy @ cant fight misty /:
Is there anyway i could get a save file and import it into my acekard2i.? Is there anything i can do to fix this.?
I think the problem is i had all the key items &I gave the stolen parts without actually
meeting the stupid team rocket guy. Please Help. I would really like to finish this pokemon game ?:
Thanks in advance <3 (:

Unfortunately I don't think you can get the Gym open without encounter the Rocket Grunt first. I know however, that during the course of the Stolen Machine Part if you go all the way up Routes 24 and 25 to where the cottage at the end of Route 25 is, you'll see Misty on a date some guy. Just go up to them and she'll have a conversation with you and then return to the Gym.I hope this helps. :)
