Money ****** from My account.

My Aunt has Bank Account with Capitec, she has saving account she uses to save money inside her bank account, She lost a cellphone and did a swim swap few days later, this happen in December 2017. When she went to withdraw the money from her saving account this year, she found out that her savings account is clean, money has been withdrawn. It has been transferred to certain bank accounts and the bank says there is nothing they can do for her. I don’t understand why cause she didn’t loose her id or bank card, how did those people know her pin and transfer the money? Her Name: Nokwanda Mzongwana ID Number: 640 ********** 083 Cell Number: **********
