Bad service

I received an extreme terrible service ever in the Randburg Capitec branch from Velli, where I got there to make a deposit and before I walked to the queue for the deposit I asked the lady by the door who looked like the help desk or enquiry desk to direct you where to go. I followed the queue for +-25 minutes which I don't have a problem with that, however getting to the teller Velli she asked for the mini slip that I was supposed to be given by the lady I firstly approached, when telling her that I was never informed of that and as I followed the queue the least she can do is to help me, she referred me straight to get the mini slip when I got back with it she said to me wait till they call your number on your slip with an attitude and rolling her eyes on me, saying that's the procedure, I tried talking to her telling that if I knew what to do I would have done it can she assist as I cannot waiting another 20minutes, she called another customer of the number that is been called like I do not even exist. Pathetic service ever by Velli
