Disgusting service

On Monday the 13th April 2020,I app**** for a loan on the FNB app,after 5 minutes it told me it was successful and sent me the quotation of contract confirming the loan amount as well as intrest etc. I then spoke on the secure chat on Tuesday the 14th asking why the money is not reflecting yet, the adviser told me that I would need to wait for 24 to 48 hours for payout. Today being the 15th I called fnb directly to find out what there problem was where I was then advised that there loan was declined. I am extremely upset as I was given a written contract confirming the loan as well as being told to wait for the payout, to then hear it's being declined send recieving no communication of this.
