a whole morning wasted due to *********** staff

I get all my statements from various stores via e-statement so when I wanted to open an account at standardbank I had to take my mom with her papers with to fica the account. I asked the guy at help desk what I should do. After speaking to a consultant he gave me a form for my mom to fill in. My mom being a pensioner didn't want to wait in the long line so I asked the guy if she could go. He then took the form back to the consultant who told him its fine she can go. After almost a 2 hour wait I finally got called up. The consultant helping me immediately said the form my mom filled it wasn't right. This after the 2 other previous people said its fine. To make it worse the consultant who said its ok in the first place now said its wrong. Claiming to never have seen it. I must say the lady assisting me was very helpful and friendly. She explained to me what was wrong and filled in a form for me. I get that there was a mistake on the form. I don't get how 2 people said it was fine when I asked. My whole morning wasted for nothing. Today was the only time I had to sort out the account. I am working all week now even on wednesday.
