I switched plan and mobile through the app, and was charged to my account twice. I called fido, who put the blame on the bank, and the bank, which says it's fido's fault. What I do know is that it was debited twice the amount it should have paid, and fido just doesn't solve my problem !! The attendant also said that it is possible that this extra money becomes credit. I do not want credit in the account, I want my money back!
