Duplicate question. Send a followup letter and/or call to ask about the status of your "grievance."
If you feel this is the "best" answer or is "helpful," please indicate. Since I am limited to the information you provide, I cannot guarantee the accuracy of the answer. You should seek the advise of an attorney who can explore all aspects of your question. This communication does not form an attorney client relationship.
This is not a personal injury question. If you think you were not treated fairly, and have the knowledge and skills necessary for the license, you need to explain that clearly in the letter. Id suggest you have someone who is a good writer help you, as your post was not very well written, and therefore confusing.
You should use the Avvo "Find a Lawyer" feature and hire a lawyer to help you locate the place where the grievance letter should be sent and what the grievance letter should say. You really should get the help of a lawyer you can meet with, explain the facts and draft a letter for you.
