Claim never progresses

You send in the form, they reply with please fill out the form. You send it back, they ask for the form again. They ask for all sorts of other documents no other gap asks for. They just seem to be sending me round and round in circles for 2 weeks, getting nowhere. Will look to switch. Maybe it's AI not answering you, but I have filled out the form and attached it multiple times, with only ever getting automated responses they recieved it, and when I follow up they say fill out the claim form... again.
