Capitec bank doesn't want to give my money back

I made an immediate payment of R1600 from my capitec bank app to an FNB account Bank: Fnb Account Number: *** Branch Code: 250655 ***... ,trying to book for accommodation and made payment to the wrong account number,yes it was my fault but now i wanted to reveres my money back,went to Capitec bank and they told me to go to FNB since the payment was paid into an FNB account when i went to FNB they told me Capitec is supposed to call them and they will be able to reverse the money back but now i feel like im being sent from pillar to post because non of these banks are willing to help and i need my R1600 back. I feel like Capitec customer service is lazy because if they could just make that one call to FNB i would have got my money back long time ago.
