Poor backoffice service from FNB

Ive been a pretty happy FNB customer untill we enetered the home loan market. During our 3 month application process with FNB I have dealt with sales personal that couldnt construct a proper sentence through email communication, three delays due to incorrect capture of forms, systems down, managers that never get back to you, transfered from person to person. The begining started off all simple and the process was communicated to us as easy by the front desk but once we moved from department to department it appears the behind the scenes people you never actually meet face to face are not equiped to do their jobs in my opinion. Very dissapointing from a brand that promotes service excellence
