Standard Bank’s unfair account lockup/worse service

I recently had my account placed on lockup by Standard bank without notice. When I call customer care is was told that I must go to the nearest branch to submit ID and proof of resistance in order for my account to be released. This is shocking to me because I have never received any notice and I have been was standard back for more that 10 years. It’s an inconvenience for me because visiting the branch requires time, which I don’t have due to the nature of my work. I am very disappointed and shocked over this encounter. I have lost trust in this bank.
