Postal savings bank cards have SMS prompt service. Forgot to cancel, the fee has been deducted. I don't want it, what will happen!

Brother, your SMS business is a one-year business. 30 yuan used this service after one year's deduction. Remember to cancel this time next year. If you cancel now, it won't be worthwhile without service. Now there is a new regulation. If the average daily account balance is less than 100 yuan, a small account management fee will be charged. You'd better save more money. Use him or cancel the account.
