I sent money at Ackermans Northmead on Thursday,sent the withdrawal number but not the pin to my mother who is in KZN then called and told her the pin was her birthyear.On Sunday she went to withdraw the money had already been withdrawn.Had to call customer care on Monday and I was told the money was withdrawn Friday(7th of May) at Kempton Park but no one had had any access to the withdrawal number except for me,my mom and the cashier that was helping me
