Complaints against Insurance Company IUM

There is a claim that has been logged with IUM since February ,It is a Third Party *** I have provided them with all they needed to further my claim, still to no avail. They have come up with all sorts of delay tactics to not further my claim. They never update you on your matter, they promise to send an assessor to assess my vehicle of which it is now May this has never been dealt with. Every time you call their office it is this excuse to the other. Last week one of their office manager claimed never to have received any quotations from me of which they received on the 15th of March and up to date they have done nothing. i am still driving with a damaged vehicle and this is causing huge frustrations for me. They are often rude and never seem willing to assist you when you call they treat you as if you more like a bother to them.
