How can I get a refund on a Google Pay purchase?
Each store has its own refund policies. With your printed receipt, the cashier will likely process a refund as they would for any other purchase. If you don't have a printed receipt, try tapping your phone on the payment reader, or give the cashier the last 4 digits of your virtual card number. It’ll often help them find the transaction in their system.
You can find your virtual account number by clicking on the PayPal card on the Google Pay home screen. Your refund will go to your PayPal balance.
