You need to contact the recruiter's supervisor immediately and inform them that you feel you have been misled. Under the personnel regulations, if you do not go to basic training, you will receive an "Entry Level Separation" and will be free to leave the National Guard. This is not a discharge; it's simply an adminstrative action that lets you out of the military and you may or maynot be permitted to join sometime in the future.
When members of the military, reserve or National Guard have served less than 180-days, they receive this kind of separation when they become in-eligible to serve.
If you state that you are refusing to ship to basic training, you will most certainly be in-eligible and will receive an ELS.
