NOT SIMPLIFIED AT ALL

I have been banking with them for a few years now. Needless to say my experience with them has been nothing but frustrating and an unnecessary expense. On 11 February 2019 I personally attended at the bank to have my OTP pin cell number changed to my new number. This was not attended to. I called the call centre thrice with endless frustration where a lady by the name of Lebo at the online banking side tried to assist but also failed as we were not advised that I needed to complete the form to have the number changed. On thursday, 14 February 2019 I again attended at Standard Bank and completed the necessary forms. Later that evening, the change had still not been done. A few calls later and I am right back to square one. I also have my fair share of frustrations with the mobile banking. I registered but when I try and log in, it keeps giving the error message that my details are incorrect. I have spent hundreds of rands in airtime as well as busfares trying to have this mess resolved and not to mention my time being wasted... I AM TIRED NOW!!! SUPPOSED TO BE SIMPLIFIED BANKING
