why would claim 3 months to be settled

3 months ago i was driven into by a miway client i am still driving a damaged vehicle. After getting a claim number from miway i was told that i would have to wait for their clients claim to be finalised before they finalise mine. After waiting two months i my miway and asked what was going on i was told that they were waiting for a quote from me i resent the quotes i had and was told an assessor had been appointed. Eventually the assessor saw the assessor. Two weeks go by and i email to ask what is going on and was told the legal agent had received the assessors report but had been on leave. Two weeks pass again and now i feel that this is beyond a joke so i email and request the GMs email and was sent the managers email. I emailed the legal departments manager who hasn't had the courtesy to even acknowledge my email.
