<prompt> Human: I ate at a restaurant where I used my debit card, but the cashier said the transaction did not go through the 1st time. She told me to input the card again. I got charged twice for 1 meal. How do I dispute this? I still have my receipt. Do I go to my bank Wells Fargo or the restaurant?  <response>: Id go to the restaurant first. Ask to speak to the manager, explain what happened and show them the receipt. If the manager decides not to do a chargebackrefund, then you go to Wells Fargo and open a dispute.Edit: You dont have to go to Wells Fargo, you can just call. :
