FNB failing to allocate a trustworthy competent Business Bankerfor my Business

I have been banking with FNB for few years ,I am disgusted by how they are treating me as Client and my Business , I have been using Northgate Branch Business Banker Called Thabo Legwete, I requested more than 3 months ago that he gets romoved completely from my profile as a business banker because is is not helpful, he is completely useless , ************* and unprofessional, he couldn’t assist me with anything for the business since allocated to me.I have a Business Cheque account,Business Overdraft,Business Credit Card and personal Private Banking account which I am going to close in 24hours if the Bank has not allocated competent trustworthy business Banker and Move my accounts away from Northgate Branch every time I been there I get send around without any proper solutions.My wife is also considering to leave this useless Bank.
