Teller not accepting to bank my money

I have two businesses close to Zevenwacht Mall and on occasion will use the bank for change and deposits. I say on occasion, as I try to avoid the bank due to a shortage of staff. At 12:45 I decided to bank R30 000 and was waiting at the cashiers as the queue at the time was not long, but the queue at the bulk teller was long. When I arrived at till 5 to bank the money, a lady with the name of Chynelle Ngoya said that she cannot assist me due to the fact that they don't have security windows and that I must use the bulk teller to bank that amount. When I pointed out to her that I did bank money at the teller before and that it was send to the back asap by the vacuum system that she also consist of, she just point black refuse to help me. When I did mention the incident to the bulk teller, he immediately asked if it was the lady at teller 5 and told me that it happens often that they don't want to help customers. This is possibly the last time that Absa Zevenwacht will see me for business as the branch is not only understaffed, but the Client Service and Tellers are now combined, so to bank, deposit or withdraw money can be so frustrating.
