FNB Taking my money in their System Clinches

I've made a payment using Mobile app - immediate card payment on the 20th Oct 23 - R500... FNB to FNB. The recipient still didn't receive it. On-Line / Secure Chat or inside a branch can not help me? I enquired and they said it was paid to the wrong card number (I verified the card number 3x)... Then on 26th I did the payment again - this time verifying the card number 5x with witnesses, and again the same thing. I've lost R1000 because of a FNB Clinch, and no-one are able to help me. On-line they will transfer you about 6 times untill they cut you off. Secure Chat takes forever - also transferring you to tell you you have to wait 21 working days for an investigation... In the branch they just pull up their shoulders ... telling you to call on-line or secure chat
