Trademark rejection needs 15 days to consider whether to do rejection review. If the agency has not informed it, or if the time has passed, it will not be able to refuse the review. The Trademark Office will acquiesce that you have obeyed the trademark office's determination, and you can only change to a reliable agency to apply for a new trademark. As for the dispute between you and the agency, you have to solve it yourself. Even if a good agent refuses, he will propose a solution without telling the customer.
