Check to see if the extra payment was put into your "available funds" which would mean that the money is still there for you for the next month. However, It is not right for Public Mobile to take an extra payment before it is due. You can direct message the customer service agent by using the following link:
Where do you see double billing? On your PM account - leave it as funds will be used on next renewal OR on your credit card - check if one of charges is pending; it will go away in a day or two.
@rosy6 If you're sure it is double billing and not a pending charge that will be removed you can submit a ticket with customer service at the chat icon bottom right of this page
