This is never a good situation - it does depend greatly on the insurance companies policies however the process is usually much more drawn out. In a regular claim your insurance company is fighting with theirs to get the money for your car. In this case they are fighting themselves so the 'sense of urgency' seems to evaporate. Make sure you really push them and keep them on their toes - just incase. This of course does not always apply but it is quite common in claims that have the same insurer.
yes. you can sue an at fault driver if his insurance company refuses to pay your claim. it would not be proper to sue the insurance company.
You do not have to reimburse your insurance company if the accident is the fault of the other driver and the claim is made on their insurance. If the accident is the fault of the other driver and their insurance does not cover everything and you make a claim on your insurance for reimbursement, your insurance will subrogate (collect back) from the other company.

A claim is a liability on part of the insurance company. If a customer makes a claim it means that the insurance company has to pay the customer for the amount is eligible to claim and hence it is a expenditure on the balance sheets of the insurance company.
If the other driver refuses to cooperate with the insurance company, you can gather as much evidence as possible, such as photos, witness statements, and police reports, to support your claim. You can also consult with a legal professional for guidance on how to proceed with the insurance claim or consider filing a lawsuit against the other driver if necessary.
You can file a claim with your insurance company. You can also get a lawyer and file a lawsuit against the drunk driver.
The fact that you don't have insurance doesn't preclude you from collecting from the at-fault party. Call the other driver's insurance company and file a claim for damages.
