Blocked account

Yesterday 03/06/2025 I made a transfer of R15000 to my grand child account, I wanted to buy shares from ABSA, within an hour I also moved that money from Capitec account to ABSA account, then Capitec blocked the account, I went to a branch, they requested proof of payment from Nedbank and the other banks where money was transferred from, I provided it all. Then today 04/06/2025 I called them as early as 8hrs,they said they are waiting for the confirmation from my Nedbank account, I called Nedbank ***** department, they said they never received any call or complaint from Capitec,and they want Capitec to call them not a customer, I call Capitec ***** department and explained my query, I was put on hold for more than 30 minutes while the consultant was referring my query, I want my money, what must I do now. Please help me, Case no ***.
