FNB please HELP ME

I've been with FNB basically my life all my business and personal accounts have been with FNB i pay monthly banking fees of 600 to 1000 on average without complaint i frequently use the temp loan facility for 5000 to 7000 sometimes twice a month but FNB won't give me a more conducive overdraft or personal loan to consolidate my commitments so I can have a healthier cash flow citing credit score / affordability issues and even thought always pay those loans on time. Mind you i took my same FNB statements and went to NEDBANK and they gave me a platinum credit card without hassle which FNB still fails to do. Since I've sc****d my way into Private Clients i thought atleast i will get better service and preferences but to my distress the service is just as poor if not worse.

My Private banker has absolutely no time to assist me with getting the benefits of a Private Banker or help me even with the most basic request of bank statements (been waiting 4 days now) i actually do not wish to even speak to him anymore.

I wish for FNB to assign me to a new banker who will listen to me be sympathetic to my cause and treat me like a valued customer i am. Fnb PLEASE HELP ME!
