I managed to reverse the payment on the app however because I'm not familar with the company I asked to be sent through to ***** so they can help me thru said they can't help me I must lay my problems to general enquires the person I was talking to refused to help me and didn't give me suggestions on who can... Overall Absa customer service didn't help me.. How will I be certain and sure that my money is safe if they refusing to help me prevent it from happening again...
