Let me start out by saying, yes there are incompetent attorneys. And there are a lot of arrogant attorneys. And sometimes they are one and the same.
Be that as it may. How did you find your attorney? If through references, you should check with them again. Some attorneys are extraordinarily busy and can be brusque with the claimants, preferring to spend their time winning a case than holding hands.
If you are really that uncomfortable with your attorney, then talk to another one about your case. It will not cost you anything to talk to another attorney. But be sure to bring all your files with you. And even then, you may end up speaking to a para-legal or a secretary, some of whom are as knowledgeable as an attorney. And do not be surprised if they tell you that your current attorney is serving you well, even if not politely.
To your specifics: I have reduced legal fees for an attorney (or their representative) who mistreats their client in front of me. On the other hand, there is an attorney I do not like at all, personally. But when a friend of mine had a case, I told him to call that attorney because, as tough as he would be with my friend, he would be twice as tough on the carrier.
Look, your attorney is like your doctor. Each person has different needs as to what makes a good fit. If you really are not comfortable with him, get another one. If an attorney does poorly for a claimant, the Board can do nothing as the attorney is licensed by the state. Licensed reps can have their licenses revoked or a renewal denied - it happened twice in my twelve years at the Board.
As for the RFA-1, it is a request to open a case that has been closed because there were no open issues. You do not need an a attorney to file an RFA-1 or any other document with the Board. But if there are complex issues and you are busy working, you would be best served with an attorney or a licensed representative (someone who passes a very difficult test and can practice comp law at the Board, but not anywhere else - they are as good as an attorney. A chapter in my book "Behind The Closed Doors" discusses these reps.).
