If the Dunkin' Donuts app charged you twice for the same order, check your payment records in the app to make sure there was only one charge. Once you're sure, use the "Contact Us" button in the Dunkin' app or on their website to get in touch with customer service. Give specifics, like your order number, the exact amount charged, the date of the transactions, and pictures that show both charges. Ask for your money back for the extra payment, and let you know when the problem is fixed.
If Dunkin' Doughnuts customer service doesn't get back to you quickly, try taking the problem to the next level by contacting them through their X or Facebook pages. In your message, include information about your case and screenshots to back it up. This will usually speed up the answer time.
