Allianz Global Assistance Travel Insurance Reviews

I had to cancel two Sphere tickets for my elderly mother and myself. My mother is 85 and decided she is not healthy enough physically or mentally to travel to Vegas. Tried to file a claim on Allianz website and it cannot find the policy despite pulling up the correct record using the policy number. Called to speak to a rep. and he agreed to file it for me but tells me that I have to have a doctor's note essentially as supporting documentation. The email I received after the claim was filed indicates that the tickets are only covered up to $200, when I paid $383. Such a scam.
