I can't be really that difficult to update just cellphone number for otp and in contact. Is it really that difficult? 24th June visited Protea Glen branch to update otp in contact. And again same branch on the 3rd of July was told about 24hours TAT. Why this TAT when we suppose to be able to enjoy benefits of self service banking? You can read between the lines to get some answers. 24 hours passed still getting errors messages that my number is not registered. Why because the person didn't capture my number correctly. How when my number is already in the system. Read between the lines. We all know what happened to this country after that. Then I was forced to withdrew money and deposit it into my account with the other bank. Fast forward 31 July decided let me visit my home branch this time may be will have better luck. Waited patiently for a good hour. Told the lady that I don't get how can something so easy can be this difficult to do. Called CC to update my old email etc now could log in no more errors to update otp. Left the branch continued with my errands. Got home trying to do my banking App error on confirmation screen I need to link app. Which one when I'm logged in. Go to my online banking same story. Again have to withdraw to do deposit to my other account with another bank. I just can't believe that Standard Bank branches don't have staff that knows their processes from A - Z. Clearly it's guessing games. In the process I have to endure all of this. Is there any volunteer that actually knows what's going on that wants to sort this out.
