Bad service

Good day

I would like to lodge a complaint with standard bank Karaglen mall around past 11 am the service was very poor I went inside the bank, the reception lady was not welcoming and I ask I want to deposit the money and it needs change she asked me to proceed to tellers when I get to teller 1 by the name of khaohelo I asked the lady I want to make deposit which the money needs change and I need to activate my change account she managed to assist me to activate the change account then she said the lady by teller 3 and she had no name tag ,she will further assist me with the deposit I waited up until she is done with the customer then on my turn she ask me to use ATM which the queue was so long. And I ask the lady why they never informed me cause the money wants change and now she tells me to join the long queue and when i asked i spent 15 minutes inside the bank cant she help me and she give me an attitude and she was silent never to bother to assist me which it's unfair. So I just want to report the bad services I received leaving the bank without any help

Thank you
