Standard Bank

I moved overseas 1 year ago and have not updated my number until a few days ago when I upgraded my cellphone. This has caused my standard bank internet banking to be disabled. I am unable to update my number on any platform, I have sent numerous emails to the respective email addresses and spent a few hours on the customer care lines. No response and no assistance thus far. I feel helpless because I cannot go to a physical branch and Standard Bank refuses to actually answer my emails or pick up. When did the quality of service decrease so much? How is senior management so out of touch with what customers are experiencing. The SB website still boasts 'banking suited for your needs' but this is far from the reality I have experienced the past year with SB.
