You have the absolute right to be happy with your attorney, and their service. If you are not happy, they may not be the attorney for you. I would at least speak to another attorney personally and see if they can offer you service that is acceptable to you. If you find another attorney you are happy with, you can always change attorneys. Don't be stuck with someone who will not communicate with you. It's your claim, not theirs.
Any attorney that attempts to give you an actual monetary answer for this, you should be concerned about. It sounds to me like there is not a very accurate determination as to the extent of your injuries, nor if you are done with your medical care. If you are not released to Maximum Medical Improvement, or no longer going to see doctors for your injuries, then nobody can accurately calculate how much your pain and suffering can be.
The short answer is that your pain and suffering is always...
No, just because you own the car does not make you liable for the negligence of another, unless there are some crazy circumstances. However, owning a car without insurance is not smart on your part. Just insure the thing, so if someone else hits it or you decide to drive it, you have yourself covered.
If you ran the car off the road by your own doing or your own negligence, you can't sue anyone. Since you didn't have insurance, you should not have been driving anyway. If someone else was at fault for your crash, you could open a claim against them, but that is not contained in your statement.
I don't really see a question here. Was there more damage to just the rear of the car? Were you pushed into another car? If Allstate will not total your car, then you should look to your own insurance company and just pay the deductible to get it worked out. If you don't have that type of coverage, then you will need to hire a civil attorney to take care of this. However, you are likely only going to find an attorney if you were injured. If you were not and are only looking to get the property...
Unfortunately yes. The car had to be dealt with and they got there first. You received the service so now you have to pay. Call them and see if you can work out some type of payment program so you both can move on.
