Worst service ever

Stand bank did not notify me that i needed to fica myself and my wife. when the 1st of the month came and i tried to move my saving from my bond account to my cheque account i found out my account had been frozen. I then call to find out i needed to fica which i did the next day and it took 2 days and still frozen. i call again and then they said my wife needed to fica as well. she did so the next day and they forgot to send her id with the proof of residence. so she needed to go back into the branch the next day. then it was promised it would be done in 3 - 6 Hours. that was 2 weeks ago and i still don't have access to my saving and standard continue to charge me for my overdraft and all the bounced payments. They are completely inefficient and unable to fix the situation. what is a customer meant to do?
