Bad Service from FNB

I am highly disappointed in the lack of service and complete inefficiency of staff at FNB Home Loans department. I app**** for a re-advance on my home loan on 22/10/2019. To date after numerous of follow-ups I still cannot get a clear answer on what the delay is. Every day there is different paperwork that is required that was never requested at the time of application. After lodging a complaint the issues are still unresolved so I have had to lodge another complaint. I changed bank accounts after 25+ years with my previous bank. I have had more problems with FNB in one month than I ever had in 25 years of banking with my previous bank. Changing bank accounts is my biggest regret ever! FNB are clearly not living up to their slogan of "How can we help you?"
