Cant get hold of any consultant

I changed banks and my bank moved my discovery debit order to new account. On friday i received a msg that the debit order move was not succesfull. From monday i have tried contacting discovery to move it. All i get is the robot and all they say is to change banking details on app or internet. I have tried multiple times but it says branch code incorrect although its correct. I have send numerous emails but got one response saying they cant help as email adress not registered. I went and registered it and send emails again and still no one helped. Now my account is suspended and still i cant get hold of any one to help me
