Poor & arrogant client service by IUM

An IUM client bumped my car in August of 2023. I submitted a third-party claim in August- claim number IUL57700 . I was requested to complete claim form and submit all supporting documents by the 8th of August. This I did by the 8th August. It in November four month later of back and forth trying to have this matter settled. The frustrating thing in this whole process is that there is just no justification for the delay in concluding this matter. At some point the appointed handler informed me that this process could take up to three years to conclude not providing any clarity on why such a process would take so long. It seems there is an effort not to pay for the damages that I incurred from the actions of their client. As to how IUM is still in business with such arrogance escapes me.
