My credit card was charge on 11/6/17 for health insurance for December. I cancelled the insurance on 11/13/17 and asked them to debit my credit card for the $323.27 they had charged me for December 2017 premium. On November 27, I checked my credit card and they had not debited my credit card so I ccalled them. They told me they could not reverse the charge because they had all ready charged it. So I am disputing the charge with my credit card company. But to tell me I had informed them to late to reverse the charge when the premium had been credited all ready on Nov 6th. I would have had to tell them before the 6th that I was cancelling the plolicy by the 4th at the latest because those files and set up and sent at least 2 days prior to posting.
