Vehicle finance approved with R300k deposit

FNB keeps disappointing me, i don't know many times have i complained about this but nothing changes, i app**** for a vehicle which was over R700k, i received a congratulatory message from FNB only to find out that i was approved with a deposit of R300k, which is insane. i then app**** for a cheaper car at Auto Pedigree with the hope that they will decrease the deposit amount, but surprisingly it was declined but Nedbank approved me. all my cars were financed by other banks, credit card offered by other banks, its very disappointing that the bank that i trusted for the past 8 years still treat me like this. i am a private client but the service i get is very terrible.
