Annoyed by your service

Was really annoyed the other day by the lack of customer service I received from Nedbank Mall of Africa Team.... I was assisted over the phone a week before hence now going in to my nearest branch/preferred branch to collect the cards as per the sms received and all....I walked in to collect a card and to be assisted with the App as I was a new user.... I get there after work and excited to get my cards as I have opened a new account and had asked for the Nedbank MyGoals Acc for my son...I also needed some kind of 32days saving thing.... Yooooh now I get to this branch that I chose only to be treated as if I'm nothing.... There was a guy named Sbusiso who was called to assist me....he dragged his feet....he was just not in the mood....no smile and just asked to see the phone for the sms..... Right there without me saying much, he dismissed me and said I'm at the wrong address and if I need him to assist he will charge me and the attitude was just telling me to go away and not even ask for more... I was defeated 😕 He did not even seem sincere to even ask what else do I need....he just pushed back my phone and folded his hands to show that he is done with me.... I felt so annoyed and just wanted to cancel everything I did over the phone with Nedbank. I wrote an email to cancel everything as clearly Nedbanks service is only good over the phone when they are selling us the products....but now at branches we get treated like we are nothing. On the email I asked to have everything canceled but even today I have no reply..... Just to add, Nedbank please take your staff who are placed at these branches for customer service training as they will destroy your image and you will loose customers/business
