Disgusting Service

I am banking with standard bank for many years and this is my first time I app**** for a home loan. My documents was emailed to the loans department on the 2015-03-17 and I found out today that my documents was only sent to the relevant sections on the 2015-03-24. I have called the loans department many times using my personal phone and every time I spoke to different people who gave me different answers regarding my application. Every time I asked to speak to the manager or supervisor he/she was on a call and I was put on hold for over 10 minutes on every call that was made to them and then i finally get so frustrated waiting that i eventually cut the call. When I sent through my application I was advised that it will take 3 to 5 working days to be finalised. It is now 9 working days and no has called me yet. I am totally disgusted and frustrated with the service levels. I can't believe it that there are such *********** people that work for the bank and does not know what's going on. I will really appreciate if someone with higher authority can contact me to resolve this issue.
