Not reliable. At the beginning, it was handled by the training institution, and the money has been returned. If you want to cancel your account (because there is too much personal information), you should not only write a cancellation letter, but also give them a photo. There is no such requirement for bank cancellation cards. What's more, they didn't ask for anything when they handled it, but now they have cancelled all kinds of opinions. Who knows what they will do with this hand-held photo? !
