Did you contact your bank to ask for your payment to be returned? If you did it a few hours ago, you will be able to get your payment credited back on your bank account or credit card. Alternatively, the credit will remain on your Fido account until your next billing cycle.
First step would be to contact your bank to see if they can still return it and the second would be to contact us to review the situation. You can contact us through one of our customer service channels here.
Hope this helps!
