Stained money from Absa ATM

I went to withdraw R5000 at one of your ATM in Whiteriver square and a stained R200 came out with the money. I Went to your branch and I was told your ATM doesn’t dispatch such. They were fast to dismiss me. So what must I do with this cash? I was looked at like a ********. I can’t provide an account number since I am an Investec client. The withdrawal was on 02 January 2019 at around 1531
