No communication regarding an ongoing claim

So I hate to do this but there seems no other way to get AIG To contact me. I was in an Uber accident on 17 April 2023. I submitted the initial claim and told them upfront that I would need on going treatment as I suffer a back/Pelvic injury. They paid the initial amount and have not responded to my emails with the following invoices from Dr's that I have paid for threatment. I have not received feedback from the Senior Personal Accident Claims Examiner. I have spend in total over 30 mins on hold trying to reach there call centre. This is absolutely ridiculous.
