Unauthorized debit order and bank not helpful

My daughter sent R600 into my Capitec account and R250 was immediately deducted from the account and I don't recognize the reference as I never authorized it. This happened on the 1st of February 2022 and today on the 3rd of February 2022, I went to the Vryheid Capitec branch to dispute but I was told at the Capitec branch that they can only stop this debit order but they can't reverse or dispute it, how come? This is clearly a **** and this particular bank cannot take action, why?
