How and where to change bank account details

[Haphazard]

Hi

I took out a sim only deal on 16 Oct. The guy in O2 shop said I could change the bank details after 30 days. I’ve checked the app, but can only see option to set up a new direct debit. (Or change payment date)

Is that what I need to do when I just need to change the account no and sort code? (Have made one payment using original account set up) 

Thanks
