If you have already paid for your current month, there is no pro-rated refund. This applies if you cancel in the middle of your billing cycle or at the end of your billing cycle.
If you are moving to a new address that currently has Arvig MultiWav service, you will be required to move to our new service tiers. This will require placing a new order which will change your billing cycle date. Customers transferring service will see a prorated credit on their first bill cycle of their new plan. Please see our Service Transfer article for more information.
