You still have to negotiate with the counter first, because the specific reason for not activating the Bank of China card for you is only clear to the counter. If you really don't have any problems, all the materials are complete, and all the procedures have been completed, but the teller still refuses to activate, you can call the customer service hotline of China Bank appropriately, and then make a complaint and ask for feedback. Or try again at other bank outlets. Maybe there is something wrong with the bank. Good luck!
