You can bring your ID card to the counter of the original agency to terminate the fixed investment of the fund 3 days before the deduction date; You can also open your own online banking, mobile phone and telephone banking services, and terminate the fund's fixed investment business through online self-service. If the fixed investment of the fund is not deducted, and the deduction is unsuccessful for three consecutive months, the fixed investment business of the fund will also be automatically terminated; It only affects the normal use of bank cards. Not the best choice.
