Ringnecks can take awhile to tame. Several months in many instances. Depends on the bird, how he was raised and what he;s been exposed to. Please, take as much time as he needs. Parrots rate of acceptance of change is glacial, especially compared to our quick monkey brains. Proceed at his pace of acceptance and not the rate of your expectations. Parrot ownership is a marathon, not a sprint. He is going to (hopefully) be with you for many years, so its important to get the first few months. years right. Try to have a positive interaction with him at least once a day, even if its a walkby with a friendly few words. He has to learn that 'only good things come from humans' (thanks 'Boats for those words!).
