Delay in application

I was at standard bank Thibault branch in CPT on 02/03/19. I app**** for a increase on my revolving credit and was told funds would be paid out on Monday the 04/03/19. Tuesday and Wednesday came , I called to customer services and to the branche on multiple times and there was no answer. I then filed an online complaint and Thursday the 07/03/19 got an email to say the complaint is being processed and after that I got a call from a Priscilla at the Thibault branch. She apologized and told me I didn't have proof of residence and I should forward that to her and she will pay the money out. I forward her the docs and asked if there is anything else and she says no the no money be paid the next day (today). She then calls me today telling me they need my latest payslip. However Saturday when I was there, they lady who assisted me said that she has all the required docs and that my January payslip is okay. I then find a way to get my payslip which is at work to be taken a photo of and then sent it off.....its been a good couple of hours.....no money and no feedback.

I am highly disgusted I'm in the service for many reasons

But the main reason is if Priscilla know that i have escalated my matter....why is she still not attending to my matter with urgency as I have mentioned in my email?! These pay ours usually take less than 24 hours! But it's taken me almost over a week!

I am at witts end and I've lost hope and do not know what to do.
