Shocking Service

I have been attempting to change my OTP option for online banking from cellphone to email. Waited the statutory 20 minutes at the Hoedspruit branch to speak to someone at the enquiries desk. Of course there was only one staff manning the desk and I was about 8th in the queue with at least another 4-5 people behind me.. When I finally got to the desk I explained that I needed my OTP option changed from cellphone to email. The lady was very helpful. She did all the right things and I signed all the documents giving permission for the change. This was on the 12th January, 1 month ago and I'm still working off a cellphone OTP. Does everything have to be such a mission with Standard Bank? I can't even telephone anyone because apparently most of your staff are sitting at home due to a COVID scare a year ago. And of course we must be patient because the help desk is suffering unusual volumes at the moment. If I could award less the 1 star rating for this page I would. Is someone going to help me?
