FNB housing finance application nightmare

I app**** for FNB housing finance in January 2018, the bong has been dragging because FNB waited for months to tell my transferring attorneys that the proof of employment that I submitted from my HR department is not sufficient after that was sorted and I am thinking all is finally done, they come back to say the policy that I submitted to cover the bond in case of my death or disability is not sufficient. I work in a bank also, I could have gotten the bond with my employer and I did but I felt since I am already banking with FNB it will be better to take out the bond with them. On top of the 11.5 % interest they are charging me for the bond, I am starting to rethink my decision to bank with FNB in case of changing to my employer.
