My mother passed away last year and I submitted a claim a few weeks after her passing as I only found out then that she had a policy with IUA under Hollard. I submitted a claim on the 18th of December and haven't been assisted to this day. They do not communicate with you. Every time I call I am told to submit one document after another. Today is the 2nd of January and they are requesting for more documents. They literally want you to call and follow up without doing anything. Very disappointed.
