Rather than helping customers with their claims, Aetna finds ways to deny them

Extremely unorganized! They lack professionalism. I submitted a claim with all the documentation they needed. They claim they didn’t receive the paperwork and are claiming that they will not aprove until they receive what they need. Their conversations suggest a punitive and condescending tone as if they have no sence of urgency to review or aprove my claim. Rather then helping their customers with their claims, they seem to be interested in finding ways to denied claims.
