ATM miscalculated my money....

I went to Menlyn Maine centre to deposit money earlier today,the ATM kept on rejected some of the notes however proceeded with a certain amount, when I balance the returned notes and the one accepted by the ATM the balance didn't add up,I went inside the branch to lodge my complain and the matter was escalated and was told I will receive an SMS,upon my arrival at work I received an SMS stating that my request was declined because they can't trace any missing amount from the ATM,I then went back to the branch to understand what do they mean if they said they don't see any missing funds,the lady who was assisting me then spoke with her manager who then advised the consultant to escalate the matter to complaints manager,I was then given a second reference number and was also told to expect a call from another consultant who will assist me accordingly however till this far no call,I can't loose R2400 due to technical faults by their ATM,I need this matter to be resolved urgently as per TCF acts,can any relevant consultant attend to my matter as quickly as possible, we're talking about money here please Capitec....
