bad service

I just called telephone banking at 8:14 & spoke to a woman called nokubonga I was successfully verified on system & I had to transact on my account via cell banking for her to assist me on account. I finished the transaction she was talking with whoever is next to her I heard. I ended up buying airtime as I felt it will cut me as I've already held on for long. I screamed hello I don't know how many times. She came through & said she was waiting I was explaining to her that I have been saying hello with no response she was talking on the background. I never said anything wrong she started shouting at me I asked why wE she shouting at me she continues with her attitude and dropped the fone on my ear. How rude and unprofessional. I demand an apology from her today for being rude and hanging the fone on me while I was still talking. If not I will take fnb further to the ombadsman as now I am not happy with her as an employee of FNB. I didn't hire her there and I never looked for a job for her to work there. She must leave her drinking attitude at the gate. That is what I did when I worked there. Get customer service stinks so early in the morning. I'm ****ed of & waiting for apology.
