Settlement payment gone missing since 2019

It has been a week since i logged a complain with Capitec bank that has not cleared name since 2019 so receive a call from them telling me to go back to DMC as it doesn’t reflect on their side that i paid then i sent all proof needed to them from DMC but still they can’t help me because there is no payment reflating ! I am so furious about this now because capitec is not willing to ask DMC to find out what happened to R52000 i had paid instead they telling me i should communicate with them and they are telling me they paid so who am I supposed to do now ? Somebody please help my contact are ***
