<prompt> Human: Dentist office said that they accidentally ran my card twice but wasnt sure if the charge went through and even gave me a receipt for the second charge just in case. Later looking at my credit card bill, it showed that both charges went through.Seems like an honest mistake but wondering if it is better for me to call the office to see if they can rescind the charge even after it has been processed, or if I should just go straight to my bank and have them cancel the charge for me instead?  <response>: Credit card disputes are for merchants that refuse to make things right.Go talk to your dentist about getting your refund - they will take care of it as soon as they can establish they really got paid twice. Show them your credit card statement.
