Poor service from consultant

Spoke to a rude lady by the name to Zuki.. i told her I am not happy with the discontinuation of Fee saver option and that we are not been treated fairly because whether I am a new customer or a customer for years it don't make a difference and I am not happy about paying a monthly service fee. She said I must send an email to the complaints department. i asked her if she cannot escalate it. She saying I must escalate it and I asked her if she cannot practise first call resolution. She refused and then I told her I am lodging a complaint about her and she said I can go ahead. I asked to speak to her manager I was kept on hold for so long and then Jack May came on the line and I was so irate I told him go and ask what his consultant told me. He did not bother coming back to me. Disgusting and I am fed up with FNB. i want a call from the business manager for FnB
