https://www.verizon.com/expresspay/#/auth-Verizon will always refund method paid, they won't send you a check unless you already started using that specific payment (I.E. If you have a $5 balance and pay $75 they will send you only $70 as a check. A payment that is completely a credit and doesn't pay any balance will be refund to the CC)
