Bad treatment

I am heart broken with the treatment that nedbank is giving me, for the past two weeks I have app**** for limit increase, I receive email requesting to accept the offer, I did as requested, I called the contact center and I was advised that the application is been approved, I waited again, I call them, they say is in back office, the next thing they send another email on top of the accepted offer, they say new offer, on top of that they keep running enquiry on my credit profile several times which is affecting my credit score, i ask them why are they sending email for me to accept offer were as I already accepted and on top of that they are running new enquiry in the period of two weeks, the next thing they will say my score is bad were as they are the one running unnecessary enquiry, last week I was told that everything is fine my funds will be allocated shortly, until today I am waiting for funds to be allocated and now is about 3weeks of the application, now am enquiring with consultant, am told application is not successfully, after accepting offer, then approved waiting for funds to be allocated, now is not successfully. Is that how Nedbank call it Treating Customers Fairly?
