Do I need a balance in my Google Pay account to use it? Google Pay balance can only be used to make purchases on Play Movies & TV; therefore, you will need to add your credit/debit card or bank account (US only) if you would like to make other online purchases. My card is added but my transaction is declining. The possible reasons could be: The card is not active or has been blocked - you may need to contact your bank to check on this. There are insufficient funds in the account - you could check the balance in your mobile app or via internet banking. I want to change the billing address If you would like to change the billing address, please contact Google Pay, or follow these instructions. How can I contact Google Pay ? You can chat, email or request a call with Google Pay. The contact options are available on Google Pay Help website.
