Lost money

I'm writing this email with a sore heart. On the 08th of May 2025 I went to withdraw children's grant at Andries Street Pretoria at Capitec bank. I tried to withdraw but the machine said the transaction was not allowed. I tried to withdraw the amount of about R2100.00 with postbank sassa card. Then I called postbank and they told me that the transaction was unsuccessful they'll report the matter and reverse my money. And then I should wait for 48 hours I waited the 48 hours past and I went to check balance the money was not there I called postbank again they told me to wait for 24 hours and I waited till date I haven't received my money. When I call they refer me they even gave me an email I emailed and explained my problem this Monday I received a call from postbank telling me that they've received my email then they told me that they will contact capitec but if I is impossible for capitec to solve my problem there's nothing they can do. They said I should wait for 10 working days. In the meantime I requested bankstatement from them it shows that the money have been withdrawn. Please help me get my money back
