Service delivery

FNB approached me on 17 Feb 2020 to inform me that I can be upraded from a premium client to a private client. During this procedure I asked the sales person who assisted me that he must increase my overdraft fasility. He said that their was LRP on my account but he will lift it for me. A banker will call me the same day to assist me in this regard. No banker called me. I phoned the next day a few times with different feedback each time. Yesterday I received call from FNB and the person who assisted me told me that I app**** for a credit card, in which I never did. I just want to increase my overdraft on my cheque account. Till date I did not received any feedback in this regard as well.
