FNB home loans service is atrocious

It took 6 months for my home loan to be approved with constant incorrect forms provided and awful service throughout. NOW EVEN THOUGH THE INSTALLMENT IS DEDUCTED THE HOME LOAN IS UNABLE TO BE PAYED OUT THE WITH NO ONE WILLING TO HELP! FNB secure chat, refers me to FNB home loans, they refer me to my personal banker (who does not respond to my emails). The personal banker finally refers me to a branch. The branch banker enquires from the FNB app and home loans and both saying that they have technician issues. After the banker again calls all the parties listed above no one is willing to help or even communicate with me. This has been the worst service of my life with this no care attitude.
