Standard Bank Worst service

My experience with standard bank has made me lose trust with this bank. Recently I've been logging calls in your call center to try and get assistance, but up until today no one is able to assist me the sad part is that they still holding my money and failing to explain to me why haven't resolved this matter.

Every time I call their call center, they keep on telling me that they are escalating the matter and that I will get a call from the consultant dealing with the case, however no one has ever called since I logged this complaint. What is it that one must do to get your attention to this matter.
