My mom accidentally sent someone money then she realizes that it was a wrong person she quickly called customer care they told her that that number doesn't belong to any account holder so they blocked it she will receive her money back within 7 days after that 7 days she received the message saying that money is out she called customer service again they said there is nothing that they can do the money was withdrawn. How come coz they said the number didn't belong to any account holder now we lost R400 while they promised that we will get the money back
