Deposited Money got stuck in ATM

On the 24th October 2015, I was depositing R1000.00 cash to Account No: *** at an ATM in Cape Town. The ATM took R900 and rejected one R100 note. Chose the option to re-insert the note. When I did that, the ATM gave an error and stopped working directed itself to the home page . I went inside the \branch"next to the ATM and a lady there made me fill in a form and said it will be processed in 4 business days. It's well beyond the 4 days and I have not got my money back. I received no reference number to trace exactly what happened."""
