Discover insure take their own time to get back to me

Their client bumped me on the 14 Feb 2025 i submitted everything they wanted including a letter from my insurance, he admitted his mistake and said his insurance will take care of it. i lodged a third party claim with his insurance, he even gave me feedback to say he confirmed everything with discovery regarding the accident but every time when i do a follow up the give me excuses they say the accountable person is on another call everyday and whenever i ask to be put through to him they refuse always saying they put an urgent message for him to give me feedback but he never does, last they told me the claim was sent for re assessment because apparently it never went to the assessors but still i never get communication from this guy despite several emails and calls. Now its been two weeks i call everyday the say the assessment report is ready but they are still waiting for him to authorise it, how long does it take to authorise? it has been months now my car doesn't even lock its unsafe to use it in public places.
