Poor service with 3 visits in 1 week and no solution to problem

For 3 days in one week 1 have gone into a branch to resolve an internet banking issue I have been having. I have been send from doimg internet banking by myself in the branch because they said I must do it there. It did not work, had to leave because they were closing and the qeue for conaultants were too long before they close, went again during the week this time they tried to help me and on the system it shows thd issue has been resolved, yet when I tried to log in still experiencing same issue. Went into the bank agsin started with a consultant, again ended up doing in branch internet banking was on the phone for almost 40 minutes, guess what absoluetly none of the people could help me. All I am trying to do is verify my account on internet banking so I can use the app on my new phone, but they can't seem to figure out how to change the email address to which the verification code is send. I am sorry, I will be leaving Standard Bank. I know they will probably not even miss me but I can't deal with this anymore. I need to make an urgent payment which I van only access through online banking not even the app, yet it can't be released because I can't access internet banking.

So long standaed bank
