No support from standard bank

We have had ***** on our account on 18 October 2025. We have lodged a case with the bank and the police witinin 1 hur. Since then we have had no feedback from the bank in spite of promises of comming back to us and not doing this. It is a busines account and since then we could not use it. The amount is over R200000. What can i do more? They just promise that it will be escalated and at is all. It is very pathetic especially since we have been with the bank for over 12 years!!
