Claims settlement alliance

Hello people.I have a question.We had an uninsolved traffic accident on 02.06.16.Has anyone ever had to deal with the alliance as a victim in an accident?The cause of the accident is at Allianz.Does your experience take about such a long time to regulate damage?Legal attorney is on board and expert reports from an MIR commissioned expert were issued on 03.06.16.I know that there is a deadline of 4-6 weeks, but the expert will also be there. From when does the 4-6 weeks period begin.With the day of the accident or only where the letter from the lawyer for the compensation claims has been received there?Our Flitzi has economic total damage ??
