Discovery insure unable to process claim of total loss

Our property and house was destroyed during flooding of a nearby River. The house is uninhabitable for at least 3 to 4 months. Discovery Insure have no clue how to handle such a complex claim efficiently. 10 days after the event and 2 assessors later that have been sent, we still have not been informed of what will happen when and what compensation Discovery Insure provides for us in renting alternate accommodation.
