No consultant has a clue on internet banking proce

My wallet was ****** with all my cards and replaced them however i am unable to log into internet banking because i don't have my old card number. Went to the Sandridge branch and they said i should call internet banking to resolve it. Called them with the reference number *** and got an email saying i should call the lost card division which i did *** Spoke to Janine Bingham who can not pick up my old card number since it was deactivated. Transferred me to general banking where they transferred me back to internet banking who also have no clue how to resolve this. I am unable to log into internet banking because no one has no clue how to resolve this. Can someone who has a clue on how things work resolve the query please
