Bad customer service

I went to cancel my laybye at East Rand mall, as most of the stuff I laybye were on sale, so most of the stuff I bought the online. When I got to the teller and she said she can’t give me cash with an attitude she will give me a voucher so I asked her since when you giving voucher instead of cash cause my last laybye that I canceled I was given cash, she said it been like that ever since, I did not want to continue with that as she was so mean and with attitude, I was upset as I have been given wrong information, why is she not trained to provide correct information, clueless, she was also chatting with the gentleman who authorized the laybye he did not even great, that is the worst customer service ever, she did not even explain how the voucher works. when I asked her she was even rolling her eyes you could tell she was getting annoyed, That’s is not professional. Bad service from the person authorizing to the teller and instead they are having a conversation instead of giving me the correct information with that energy she had for the supervisor or whatever his position is.
