I missed a doctor's appointment in he state of Viriginia and the doctor charged me a $100 no show fee even though I explained to him it was an emergency. He charged $100 on my Amex card and I told Amex that I wanted to dispute the charge so Amex sent him a notice asking him to provide evidence that his charge was legal. The doctor failed to respond to Amex and me and thus Amex ruled in my favor and did not pay the doctor. Now, the doctor's lawyer sent me a message saying that I owe $300+ (including the original payment and attorney fees) within 30 days or a suit will be filed against me.
