WORST claims process

I wish I could give them less stars. As I doctor I have never been more frustrated. EVERY week I WAIST at least 1 hour of my time following up on claims not processed, not paid, paid incomplete! I am fed up! They NEVER give feedback on ongoing issues and if you ask to speak to management the answer is always to send an email to info@discovery because they don't have access to any senior staff! Absolutely ridiculous! They wrongly reversed a claim and I've been struggling for months to get my money back!
