Appalling home loan application process and service

Appalling service for existing clients on home loan application. My husband and I app**** to Nedbank, ABSA and FNB for a home loan. We are existing FNB clients, paying high fees for better services and had the worst experience applying for a home loan with FNB. Firstly, the entire process is a painful one, when you can only apply through the app or manually have to complete a form and hope a consultant will come back to you. Other banks were pain-free online applications, as soon as I saved my application without all of the documents, someone got back to me. I requested a call back from FNB which took around 24 hrs for someone to assist me. Moving on, Nedbank took less than 48 hours to process the entire application and provide us with detailed feedback. ABSA got back to us within the same day to request further documentation and within 3 days they were able to provide a conditional grant. We are now on day 12 with FNB, who have requested payslips for the second time after they were originally provided and further documentation, which other banks requested within 12 hours. I cannot believe the comparison in the level of service and am shocked at how FNB treats their own clients, needless to say we will both be moving to a bank that clearly provides a service to it's clients.
