If you are using us for the first time this month, we take the $5.99 monthly fee with your first installment. After this, the monthly fee is charged on the 1st of each month if you have active bills with us on that day.
If you do not have an active bill on the 1st, you will not be charged- it is free to keep your account open if it is not being used!
The monthly subscription is a flat fee that is always $5.99 no matter how many bills you have active at any time!
You deferred a bill on March 5. This is your first bill with us for the month, so the $5.99 will be included with your first installment. On April 1, you have active bills on your account, so the $5.99 monthly fee will be debited.
If you were early with your payments and paid all remaining installments before April 1, then you will not be charged the subscription.
