Hey @bharat129,
Welcome to the Community!
I understand your confusion as you were advised to wait for the final invoice before making a payment.
However, the $25 administration fee is charged when registered to pre-authorized payments and we try to process a payment which is refused for different reasons by the Financial Institution. If there are insufficient funds on the first withdrawal attempt, 1 more attempt will be made 7 days later and an administration fee is charged after the second failed attempt.
I'll send you a PM to have a closer look at your account.
Talk soon!
Hey @JayKayAay! We'd love to clear some things up 
First off, do you have pre-authorised payments via a credit card, or your chequing account? The scenarios are a little different for each.
For MACC (Monthly Automatic Credit Card) :
- The amount due is automatically withdrawn from the credit card.
- Retry Schedule for Declined MACC Payments:
- 1st Retry: 7 days after initial extract
- 2nd Retry: 7 days after 1st retry
- 3rd Retry: 7 days after 2nd retry
- If the payment declines on the 3rd retry, we charge a $25 administrative fee. (not applicable for Quebec customers)
For PAC (Pre Authorised Chequing:
- The amount due is automatically debited from the bank account.
- For declined payments, the 1st retry attempt is 7 days after the initial withdrawal date.
- If the first attempt for the payment was backed-out manually by the bank with a delay, the 7-day retry schedule wouldn’t happen.
- If the payment declines on the 1st retry, we charge a $25 administrative fee. (Not applicable for Quebec customers)
For each scenario, the time where the $25 fee is charged can vary. There are also some exceptions where the $25 fee may be charged after just one failed attempt. These are all unique and we'll need to check your account in order to provide the information. If ever this happens again, please contact us so that we can look into it.
