Terrible Customer Service

I just had a very terrible client service from one of Capitec' Teller in Rosettenville today (26/02/2019 - 11:16am). Teller screaming at me wth not even courtesy to ask me to sign a slip after depositing, just a mere " sign the slip! I even asked the Teller if there was maybe anything wrong i have said or done to her, but all she said " i am just emphasising my point - i want an account number NOT the cell number! This is strange to me as we always use a cell number to deposit money in a Capitec client's name, but today she had to give me grief. I hope Capitec can train this Samantha lady in customer service.
