Reversal of the money

I mistakenly deposited the money using the *120* to a wrong number then it ended up going to the wrong person the cell phone of this person it's not longer existing in the network but Capitec bank it's saying the can't reverse the money they need permission to the person that they can find and the money it's still there in the account but they don't want to reverse it even though they have all the proofs in front of them.
