The worst service I have ever received

I tried 2 deposit R100k into business acc at the Unisa branch as I am an employee there & ws treated with intolerable suspicion. There is no where indicated that the branch does not take large deposits & was made to wait for team leader to approve deposit who again treated me like I was doing something wrong which was totally confusing because I thought that is what Standard bank is in the business of doing. When teller was counting the money while complaining the whole time abt being made to count so much money she started waving around R100 note saying it was **** you can see it by just looking at it. I found her whole approach very distasteful & rude. While disputing this, team leader was then called who had gone to get lunch & had to wait for her. On her return she said the other 2 notes where fine but 1 was not. While I called main acc holder 2ask if I shud continue with trans the teller then proceeded to deface the R100 note by stamping all over it. Even if that is SB process there is a certain tact that should b used when dealing with such situations. I refused 2continue with transaction she then placed defaced note in the middle of other notes & when objected she was rude.
