Standard Bank is useless

Standard Bank and their Call Center is the most useless entity! There is no direct number to call a branch. You phone the call center , hold for ages, only to be told they can't get hold of the branch. I asked to be put through t a senior manager - no they can't do that. I asked for the call center manager, no, I can't speak to them, I asked for the consultant's surname , no, he can't provide that either! While "service" gets worse and worse, Standard Bank managers hide behind a screen of anonymity. Try to find out about something on your account, and after holding for 20 minutes plus, you are subjected to a barrage of security questions, which they admit are sourced from 3rd parties. You answer honestly and then are told you've failed the security check. You must go into a branch. When all the time we are told about the "convenience" of branchless banking? And then they block you for 24 hours too. Here too, you ask to speak to a Manager to report this, no, managers aren't available to speak to clients. Well, my high service fees are paying these "Manangers' " salaries. I am totally disgusted with the low standards of service and the rude call center operators. What does a client need to do for someone with authority at Management level to take their grievances seriously?
