Customer service is non-existent at Delta Dental. I've emailed them via the 'Contact Us' form on their website over fifteen times without reply. I've also emailed them through their customer service email line without a single reply. I finally managed to cancel my contract with them (1 more year to go because they auto-renewed without reading any of my requests to cancel). Their website and customer service line is not handicap accessible, so good luck and have someone else call for you if you're hard of hearing, like I did.
