I received an outstanding dentist bill that the insurance did not pay. I only had a $27.00 balance before this bill arrived. The dentist office must have taken my information from the previous debit card authorized and used that information to debit my account for the full amount of $76.64. I called the bank and informed them that I had not authorized a $76.64 payment to this dentist office. The bank agreed to reverse it. I called the dentist office to inform them that the unauthorized debit will be reversed and they will receive a payment in the mail. I also informed the dentist office the payments will be made by money order. Was it legal for the dentist office to debit my account without my knowledge?
