My money back please

My sister and I went to Northgate standard bank on the first of May 2020 to do deposit on the atm, amount of R4 000 R3000 went through then R1000 stuck in the atm, we call them they gave us a reference, we went to the branch they gave me form to fill and told me that they need to count the atm, I went to the branch several times they always says they are still busy with investigation, and we had to fill onother form, not to mention how much I spent to go to Northgate to be on the quee for almost 4 hours as pregnant as I am, I understand is during pandemic, but this is unacceptable, can't they check there cameras is almost 3 months and 3 weeks still waiting for my money, good people R1000 is alot of money, the service is so horrible, I'm so disappointed . Just want my money back!!!!!
