Baddest Insurance in claims/ communication

car taken 28 December. Agent assigned to the case goes on leave without notification. only when i made the call as they were not communicating, that's when i got to find out that the agent went on leave and conveniently another person is assigned on the day of my call. they claim they were gonna call me. they never did. i received only an email from the newly assigned agent after i complained again after 2 days of non communication, her email stating they're awaiting assessor report. that is 5 days ago. today 13 Jan 2020 I made a call as no one is communicating still. The agent that answered the call is saying they're still waiting for assesor report. How long can that report take? weeks are passing and my claim hasnt been approved. soon the courtesy car will need to be returned and i will be left stranded. That is totally not cool at all.
