Hi again, welcome back. OK, you can find out the reason for your denial in the denial letter that the SSA sent you. When it sounds insulting or incorrect, try not to be too worried, because those letters usually use standard canned language.
Now, you may want to urge your lawyer, in writing, to respond to your messages left - and consider documenting when you called and left messages that were not responded to. Explain to him that you have asked XYZ questions, you still have them because no one has responded, and mail it certified r.r.r. They may take it seriously once they realize you are documenting the lack of communication. Lack of communication is one of the more common ethical charges against lawyers, and I am sure they don't wish to be accused of that.
You mention ODAR, so it appears you are waiting for a hearing. You should have gotten a letter from ODAR when you first appealed, acknowledging your request for appeal. If there is a "cc: LaTour", then you know that Bill is noted as being your attorney for this appeal, which means you signed and he submitted a 1696 already. Several weeks or a few months before being scheduled for hearing, you should receive another letter from ODAR, tell you your file is ready for review as all evidence has been exhibited. You can call the number on those letters and ask the ODAR to send you a CD disc of your file. Then you will know what is in your file. You can also see in that if Bill submitted a 1696.
If you decide you must terminate the relationships with that law office, I suggest you make sure you have another lawyer on board first. It can be hard to get another attorney because the second attorney will have to share the legal fee with Bill unless Bill withdraws AND waives fee. Most attorneys, while they will withdraw, will not waive fee. Some latter attorneys won't take a case if they know that they are going to have to share an otherwise already very discounted legal bill. However, some of us do accept them, so you just need to find one who does. If you do change attorneys, you want to let Bill's office know, so they don't continue to put more work into your case, which they will seek fee on should you later prevail on your case.
In the meantime, as you decide whether to keep Bill or terminate and get another attorney (get another attorney FIRST, then terminate), you will want to continue being VERY diligent as to your medical treatment for ALL impairments, generally. You want to tell your doctors all of you complaints, and how your impairments are affecting your day to day activities. You want to keep Bill advised of ALL treatment. If you are unsure if he is getting your messages, or to otherwise protect yourself, communicate to him in writing with some sort of proof of receipt. Note that the Judge does NOT review your case until right before your hearing, so while we SEND in the medical records once we get the updates right before hearing (unless you wish to pay for more frequent ordering, which is entirely up to you, your budget, etc.), they just sit there for many months. But the lawyer is likely putting together a case theory, pre hearing brief or memo, etc., which changes and evolves based on changing facts and evidence, as the months go along. Almost everything the lawyer does during this 1-2 year wait for ALJ hearing is quietly behind the scenes, so you will be unaware.
You may also wish to reread your contract with Bill, to see if you have any obligations you may be unaware of, just to make sure you are doing your part.
