Unhappy about the withdrawal of cash send to my daughter

On 02/03/2026 I send r2000 cash to my daughter who is at university. I forwarded him copy of slip so that she can use it when making withdrawal. Apparently on the 04/03/2026 she went to the STD Bank ATM, only to find out that the was already withdrawn. Who makes withdrawal she doesn't know, so to me. On the 05/03/2026 a visited PEP store Lephalale to enquire about the withdrawal. They call their customer Centre for more information and they said money was withdrawn at Orange Farm, standard Bank ATM the same day I send cash. When I asked them how possible, only to find that the cashier/telller when she asked me my contact number she entered the incorrect cell number even though I gave to her 6 times. (Believe you me..6 times) At the call centre, they said the person whom make withdrawals change the PIN. HOW possible, I'dont know. Now they said I must go to the nearest police station to open a case and they will investigate. My word. Who is fault is this. Please I need help
