10 years ago, I had dental surgery for less than $1000 yet the doctor still returned my post-op phonecalls and provided consistent, thoughtful communication, even a year later when I had questions about complications.
If you're spending $15,000-$20,000 on a surgery, you better believe you should expect customer service and treatment built into the cost. And if there are failings thereof, you should hope that the doctor consider it his duty to address them and apologize for them if necessary rather than dismissing them as "nonsense."
