Bad customer service from call centre agent

Good day,

Today I had an incident where' by I called the call centre because I wanted to know the final balance of my account so I can settle the debt since am working now to my surprise as I tried to explain to the call centre agent my query she was rude to me not once but twice when I called I kept calling to see maybe I can get someone more rational to speak to who is not going to shout and be rude toward me to my frustration it became and screaming and shouting match as I proceeded to ask her why is she being rude and disrespectful towards me n not listening to what I have to say she hung up on me that was a female I didn't get her name either, I then proceeded to make a second call again to get someone to speak to a guy picked up I tried to speak to him aswell as I tried explaining to him what my call is about am not sure weather he was having a conversation with someone next to him or stoping me from explaining my self I then proceeded to ask him is he gna let me speak or must I let him speak then a whirl different argument erupted from there on wards am very unhappy with the service I got from your call centre agents that is not the way to treat customers or the way to do business when someone wants to know a simple thing relating to their account am very upset to say the least I was at work when I made the call and it ruined my whole day id appricate it if those agents are called to order about the way they behaved because I had to waste my work time to argue with them over nothing all I wanted to know was my foschini balance so that I could settle it and that didn't go as planned they should employ more competent stuff
