Shocking Service and support

Been to the bank 2 times, phoned 2 times and send 6 emails. all of this in one week. Been at the branch seeing the Manager, Gerhard, he assured me that he will escalate it. Ilishia sat with me and informed me that she will follow up and get back to me. Informed me that the EEd was offline but will follow up again and phone me. This was Wednesday. Phoned Thursday spoke to Elisna (Sales manager on call in) who OFFERED to phone back. No luck. Phone today again just to hear she (Elisna) had to hold on to long then dropped off but still nothing resolved and no call back. FNB Willowbridge is Shocking. Who can I call or ask for help???
