Rude, sarcastic and disrespectful

My name is B Mbedeni. I was at FNB in Motherwell shopping complex to open a savings account on the 5th of May and was assisted by a lady named Lilitha. She opened the account for me and also updated my cell phone banking number. I went home and opened my online banking app as per normal and to my surprise, my old PW was declared as incorrect, so I kept entering the PW multiple times until it was blocked. I had to reset my password but the otp was sent to a completely different number. It was not my old number, nor was it my new one but a random number which started with 072. I had to go back to the bank on the 12th of May using my own money and was assisted by a young gentleman who handed me over to someone else while I was asking for his assistance. The next agent was the rudest, undermining and sarcastic girl named Nobahle Ngcingwane. I told her my story and entered the PW which didn't go through using their PC and her response was, as I qoute "it's your fault, you are the one who entered a wrong PW". I was angry, frustrated and annoyed, I told her she's not helping at that point and she continued to say "next time check the PW when you enter and make sure it's the correct one". I asked her if I could speak to the gentleman who passed me on to her, she then said "he's busy with another customer". I asked for her name and she didn't give it to me at that moment. I went and sat down to do what I was doing on my phone. She then came to me and showed me her name tag and said "you wanted to know my name". That attitude and confidence just showed me she's been doing this for a very long time and nothing had ever been done about it, hense the confidence to go back to me and provoke me in giving me her name when I had let the whole thing go. It would have been much better if she had apologized for the inconvenience caused by the other lady or rather explained what had happened and whose number was under my profile, instead of telling me that she doesn't know that number and the lady who helped me in the 5th of May is also busy with someone else, and the fact that "IT WAS MY FAULT"... FNB needs to teach their agents how to handle irate and frustrated customers and not just people who work for the sake of working. This response would have been much better "I'm afraid the previous person is busy at the moment and I'm happy to assist, investigate and figure out what had happened, I will fix it for you, my apologies for the inconvenience caused". That's customer service and not rocket science. I entered the same PW I normally enter when I'm using my online banking and didn't know I needed to use another PW when I'm using their other app, whatever it's called. I'm still fuming while typing this because being disrespected when you are the one who had been inconvenienced and didn't get a proper explanation from people who "should know better".. Is totally unacceptable, at all.. Period Contact me on ***, email adress *** ID *** urgently with the feedback regarding that rude person and the *********** staff involved.
