If you were expecting a large bonus but you received a small bonus, and you paid income taxes on the small bonus, then you have paid the correct amount of tax. It doesn’t matter why the bonus was reduced. If you believe that you paid tax on the large bonus that you did not receive, it might help you to meet with an accountant to review your situation.
If you are dissatisfied with the bonus procedure, that is not anything that a CPA could fix for you. You would have to discuss that with your employer, or your state labor board or a labor attorney, and it would depend on the laws of your state and whether or not your position is covered by a separate contract.
