Bad client experience

So we app**** for a loan on the fnb app and got approved for a higher amount but opted to take a smaller one. We got approved and went as far as getting the documents sent to us and got a message on the app confirming that the loan is approved and the money is on its way. This was on Friday 26th January 2019. the money did not come through and no follow up was sent until a message came through saying the loan was declined. How this is baffles me as we have communication to the contrary. we just called this morning to enquire and they reiterated that it's declined but cannot account for why your system approved it. FNB prides itself with being technologically ahead of other banks but I have proof that it is actually neither advanced or better. My wife is a premier banking client and we were using the banker service on the app and all we got was "sorry, we cannot assist with personal loans". with the fees that are charged, it is not worth it. we are moving our banking elsewhere
