Standard bank ***** department taking incompetence to a whole new level!

I really cannot carry on like this anymore.... your ***** department keeps on blocking my transactions, then I need to call in to get it unblocked. Then, even after they say that they will unblock it, it is just blocked again the next week.... Then if I log a complaint via email the ***** department say there is no block.... but again today my transaction is blocked, only this time the agent could not authenticate me, despite the banking app authentification done, and said I must go the the branch.... For crying in a bucket!! I really cannot anymore? I really dont know what to do anymore. The level of incompetence and frustration has no end!
