Absolutely Ridiculous Lack Of Feedback

I have been dealing with IUM for the past 2 months to resolve an accident claim caused by a client of IUM. The main issue that I have is the fact that after multiple requests made telephonically and via email to get an update status on my claim I have been told that I will be contacted and updated on the same day, this call and/or email has still not yet been made to me and even after a month of submitting all the relevant claim details I do not know what is the status is on my claim and at this point all of the vehicle repair quotations that I had to get are already Null and Void. I can Understand that people can get extremely busy and at times forget to contact a client, but to do so several times over after stating that you will update someone is just unacceptable.
