IUM is a ****

An IUM client bumped my uber Car in August. I submitted a third-party claim in August- claim number IUL42468. I was requested to complete claim form and submit all supporting documents. This was done, then was asked for two qoutes. Submitted late September. Then my request was confused with someone else's claim, that was corrected early October. Since then been calling weekly to get told the matter is being escalated and that because I am not their direct client, I am not priority and IUM has up to 2years and hold onto my documents and drag their feet. Continued following up today and was told the same story. IUM is the worst company and terrible at client service. My request is still not sorted while everything is clear, they are just stalling finalosing the claim and paying out..They are just ******** clients for 3rd party claims as they refuse to pay when an accident happens.
