Trying to change my payout settings for my marketplace earning!

Hi, It has been like a few weeks I emailed the accounts department and the support to change my payout settings. I already emailed them my bank account details but still no reply and nothing is happening. I really need to change my bank account details as soon as possible. I would appreciate help and support on this situation. Since my bank accoutn details sections is locked I can not edit and change it.

Best
