Bad service!

I went to Absa bank yesterday during my lunch break in overport city. I stood in the queue and waited my turn to get to Molly, at the customer service desk. She calls me to come through, I go I greet, half way through me greeting her and trying to explain my reason for coming into the bank, she rudely starts talking to her colleague. I waited for her to finish and then tried to explain what I needed. She continues talking to her colleague and I started getting upset. I needed to load my sons school he acc. account to transfer his school fees. She then tells me to put my card in this machine, and doesn't give proper instructions and it doesn't work. I am very upset. She was rude, and then she waits for a manager to come authorise this, which would not have been a problem, had she spoken to me like a customer and paid attention to me, I would not have taken my card off her desk and walked outside to the atm and did the deposit like that. This acc is my sons maintenance account. yes it doesn't have millions, so does that mean I shouldn't be treated with respect? Bluff branch has a far superior service. This is utterly disrespectful.
