FNB's 48hrs is a lie

I submitted all required docs on Friday, 05 Feb 2016 to FNB Butterworth branch and was promised feedback in 48hrs but it's already 10 Feb 2016 and no feedback has been received. I've made follow up calls since on 09 Feb 2016 and I've been promised feedback which never materialised. The only response I get is that my claim has gone for validation which has no TAT and I've had to indefinitely postpone a funeral because of endless stories from FNB. The 48hrs TAT has suddenly turned into an indefinite Validation process.
