very bad customer service

I must say,standard bank has as very bad customer service and they all do things the way they wants. On the 18-02-15 I received as call from zanele hlongwani and I asked her call me after 30 min as I was Busy at the time, she was rude and told me I should reply to my emails. When I went to the branch I fine that my case has been closed and she wrote she spoke to me. Since I have been waiting for feedback or solution from the 1st from standard bank and I must say till today I have no joy with their service, every time I call someone will tell me someone was supposed to do this...I'm really feedup now
