Question regarding the verification of bank accounts

Hello everyone,

Quick question: In order to link and verify my (German) bank account, I had to transfer 3 Euros to the data that was given to me in that little window that pops up when I want to withdraw Euros via SEPA. I would like to know 3 things now:

1.) How long does it usually take to recieve the amount and verify the account on Binance?
2.) Is there a possibility to check whether the bank account has been added or not?
3.) How should I proceed, if I get no response from the platform?

Thanks in advance and have a nice evening!
