FNB giving nighmare on Overdraft application for Private banking client

I app**** for overdraft on my cheque account on 29th March 2019, after speaking to Private Banking consultant. Till now there is no proper response as my request was going from one consultant to other. They asked me for my payslips which i did sent twice along with filled in financial information form which I am asked to fill and send. Till now i emailed some 10 times.. but there is no proper feed back. I am contacting 3 consultants like a head less chicken.. and still the issue is not resolved. I think i need to switch my bank NOW. I am a private banking client. When i called the consultant to apply for Overdraft, they said that FNB is running a campaign called Fusion accounts and explained me that I change to Fusion private account..for which i said ok. With in hours my account was changed to Fusion Private account from normal private client cheque account. But the overdraft application is going here and there but NO FEEDBACK till date, if I call the private bank suite it takes ages to get hold of a counsultant. I am soo frustated and annoyed of the service with FNB.

PS: I need feedback on my Overdraft application, as I need to pay for my Computer Course which i need to enroll. Can Someone help me in this matter urgently??
