No care whatsoever for the cash I lost depositing on a Capitec ATM

I have been a Capitec client for 13 years and this is the first time I'm genuinely considering changing banks. I deposited R4300 at Sam Nutli mall in Katlehong days ago and the ATM malfunctioned. I have been running from pillar to post and the only response I get is that they're still investigating. Whether you check cameras, speak to the employees at the Sam Ntuli branch, or run a check on the ATM at the time this incident happened should not take days for an issue that's clearly your fault and one your employees promised should be sorted within 24 hours. Gross incompetence.
