Bad Attitude at High Level

I went to the Absa Southgate to Fica my documents, I stood on the queue for a good 25 minutes after the reception had confirmed that I have the right documents. To my shook, this lady by the name of Zanele Ndaba said to me can't use my statement that was emailed to me. Said to me I must go get a bank statement and back to the queue, I said I will get the statement in a minute but why must I go at the back of the queue,mind you I was on lunch and my time was running out. I asked her to call someone senior she said one is on lunch and another on a call so there's no one senior. She was not even apologetic and didn't want to listen to me. Is this how absa threat customers? I have never seen such a bad attitude in my life, I ask myself how is she dealing with customers with such an attitude. I will never set my foot at Absa thanks to this lady. I wasted time which I didn't have. I need a written apology from Absa and from this lady. I can't be treated like a dog and shouted at in front of other customers. I then went to the back of the queue and stood there for another 20 minutes. I went to a lady by the name of Sthembisile Masuku, she told me I have wrong documents. I left.
