Your call centre has zero knowledge

I have been trying to do an application for 7 days now with fnv. Lifestyle financial services who ia servicing your clients do not know how your system works, and i have not been assisted until 3 days ago. Now when the application is done, nothing has come out of it . I have been with fnb for many years and this is unacceptable. I have spoken to a minimal of 7 people, and they keep dropping the call when they dont know how to answer me ot say they will call back and they dont.
