Other clients are more important

I have been trying to log onto my on-line banking, however, I entered the incorrect details three times than it blocked. I tried to reset the user ID as well as the password, however, it gave an error which also requested that I call the number ***. I called that number and I got through to Tsholofelo who is in the technical team who has such a disgusting attitude for a person who is a consultant. I explained to her what is happening and she told me that she needs to know the error that I was given, I tried to recall it, however, I was not in front of my PC as I was calling from another phone. I asked her to please call me back on my cellphone in-order for me to go back to my PC so that she can assist and she told me straight that they are busy and she cant call me back now. Which is ****, the customer comes first and that,s it. I work in a call center and if a clients is requested to be called back, you do that. She told me she will call me later. I'm so disgusted at the service I got from her, even when I requested for her name her tone of voice changed. Clearly if they cant assist me why not switch banks cause clearly they way too busy to assist their client
