Beyond pathetic service from the team leader Tellers

I send my guard to ABSA Thabazimbi to do a new school registration deposit payment, the teller captured the reference incorrectly, I then returned him for correction,he was sent back as the team leader Tellers Adele Lamprecht refused to authorize the deposit correction for their own error, I have send her a text,on her response she didn't greet me and she was unapologetic, she said they captured what was written and that's all, so this is it, ABSA is a company belongs to certain people and certain clients are not taken to consideration, this service is beyond pathetic as I have to suffer on their account and provide me with ruthless and arrogant service. This is now way too much!
