Standard Bank allowed ******** to take my money but can't refund

I was the victim of debit card ***** last week. I reported it, was given a reference number and told the ***** department would contact me within 3 to 4 working days. It's been 5 working days now - and I have not received any communication regarding my case or an explanation of why money just vanished from my debit card while it was in my possession. Yesterday I tried calling the customer care number 0 had to phone a total of 4 times. Either the rep cut me off or transferred me and in the process I got cut off. On my last attempt I called the Complaints number and I was promised a phone call from the ***** department - but alas - it's been 24 hours later and still no phone call. My online and app banking is blocked so I can't make any transactions and no one is willing to help me. Unable to go fight this myself at a branch.
