POOR SERVICE DELIVERY

I was in a process of depositing money on the FNB DOT CENTURION on the 2nd of November 2015, Immediately after I entered money in their machine the transaction was cancelled and the machine only released a slip to say my deposit was unsuccessful, I then went inside the bank and explain to them my story from there they gave me a form to fill my details of which I did and they told me they will contact me during the course of the day not later than tomorrow, I have been calling them since the 5th and I am always told they will attend the matter as soon as possible and that I have to call them back again if I do not hear anything from them and when I call I always get a different consultant who'l tell me they don't know about my story and they don't know the people who assisted me as they don't have those names in their section,I called again on the 10th and I was told that the process takes 7 working days , I called again today and when I explain to the consultant I am told the same story that they do not know the person who assisted me last time, don't know whether I'm given wrong names or what but that's the worst service iv'e received at that branch!!! All I want is my money!
