Well since you both have a problem, you may end up getting grey hair before it's all over. First off never conduct business by phone without a written follow up. Most companies are quick to cancel things over phones but some are still of the mind that it needs to be in writing. You on the other hand were obligated to youreself, if no one else, to go to the bank and cancel and automatic authorizations you started. If GE Money (Care Credit) doesn't have a written directive, they aren't likely to stop making money by racking up the charges and fees. What you must do, is first go to the bank and file stop payment papers to Care Credit. Then you need to contact the doctor and make sure the Care Credit claim is indeed paid off. Then you have to send a letter to GE Money Bank and Care Credit both telling them you are not going to be responsible for their error in following up your request. Give them the date you made your full and final payment, the account number and when the first payment was made and again the final. Relate you called Care Credit and was told they had erred and would correct it. Tell them if they can't fix their mistake and apologize, you'll be more than happy to take them to small claims court for fraud, report them to the state banking commission and give the story to the local investigative reporter on TV. When you show them you're ready to take them on, they realize that they've run into a savvy consumer. The adverse publicity of a reported just calling them is enough to make them cry uncle plus if there a chance they may lose in court, they suddenly come to their senses. Make sure you have your ducks in a row and start writing. Give them thirty days and if no response, send another letter to the CEO.
