Astonishing service

Wow the way FNB is sending me from pillar to post is really frustrating. Money was taken out of my account on the 20th September and I was sent to and fro until I was able to log my case on the 3rd October of which they told me the investigation will take 5-7 working days alright no communication whatsoever about the process. Did a follow up on the 10th they told me they still busy with it they will contact me they did not contact me in the 16th did a follow up again and the lady I spoke to told me that they are done with the investigation and that they could not find anything out of order and that my money will be in my account within 48hours but they will still proceed with the investigation I'm like OK good. Today it's the 19th I called them again now this lady tells me that they are not done with the investigation and that I should call them on Tuesday REALLY!! Wow I did not expect this kind of treatment from FNB.
