Declined for a revolving credit plan

I visited Fnb Montclair/Mobeni branch in Durban on Wednesday 19 February 2020 to apply for an increase by R15 000 in my revolving credit plan and was surprised and disappointed to be told that my application was rejected.

I asked the consultant who was helping me why was my application declined but she told me that she could only tell me what was written on the system and nothing else. After that she said they could only offer me a loan or overdraft. After I told her that I was not interested on those products she together with her Fnb system further insulted me that I qualified to be upgraded to private client and to apply for a bond as I am currently on premier and yet I didn't qualify for a small loan. I wonder if this is the way they answer to their 'How can we help you'. It is obvious that at FNB their credit status means nothing as my Fnb account is more than 20 years with green ticks on time with fnb and proven credit track record.
