Refusal to help a customer by STD Bank Manager (Campus Square)

I went to Campus Square (JHB) Standard Bank (20 Sept 2022), and I must say I was really disappointed with don't care attending towards me by the manager. I want to deposit R328 to JHB City Park, so I went to the teller as I had R350, and would have needed change. The teller refused to deposit and insisted that I must go to the ATM and round off my payment to R330, so I asked her to call her manager. I met the lady and she introduced herself as the Branch Manager and her name was Kershia Mbasa. She also insisted that I do as the teller instructor me and the was nothing she could do. I told them that I don't have R350 and I don't have change with me, she wasn't interested in my story and instructor one of Consultant to go assist me with the deposit. I had to overpay and pay the whole R350 as they were insisting that won't help me because STD Bank doesn't do manual deposit anymore. I really am not happy with where approach towards this matter, which resulted in me being short changed.
