CashSensd Query

I'm extremely disappointed with the bank. On the 29th of February 2024 I sent a cash send to my young brother as I normally do on the monthly basis, this time around the cashsend automatically sent it as a chatwallet transaction. My brother got a WhatsApp message that I sent him the cash but could not receive the money because of the error every time he tries to scan his face to register. I went to the Brackenfell branch and they logged the case to CashSend Queries, the response came back 3 days later with a number to call for assistance as they cannot reverse my money . When my brother called the number they were unable to help him and told him the money can only bounce back to my account after 30 days. It looks like all the staff is clueless about this Chatwallet thing this is so rediculous from the big institution like Absa bank.. I need my money back please
