bad attitude

i went to capitec bank at park station johannesburg today i only needed to up my limit and to let them know that i'm not get their sms of my transaction with them so when i went in i was quickly called and went to the guy by the name of EMANUEL he was very rude from the beginning of our conversation when i ask him question of what was happening and how it might have happen that i'm not receiving any sms of any kind from my account he would tell me that i must shut up if he talking and listen to what he is saying ,he did not want me to ask about the issue of my sms or maybe he also did know what to do as well as i thought i would get help from them as i am a client to them
