There are no cancellation fees with a month-to-month Moose service.
However, there is a cancellation fee if you are on a 12-month contract, and that fee will depend on how many months you are through your 12-month service. To work out the potential fee for disconnecting a 12-month service, please see the relevant critical information summary for your plan.
If you are going to cancel a service, it is best to do it towards the end of your billing cycle so that you will receive the full value for the month you are in. Importantly, you may still receive another invoice for excess usage charges that you may have incurred in your last billing cycle.
