Arrogant Security guard is the branch manager of signet terrace standard bank

I made a deposit at the signet terrace branch, I had asked the teller what time they close, she told me 15:30. Upon returning at 2:30om, the arrogant and rude security guard said the branch is closed at 2pm. Who is running the branch?? Standard bank or the security company?! Put a clear sign on the door if you want change hours on how you feel on the day!
