****py & non accountability service

My sister went to an ATM inside a checkers hyper to withdraw a cash send of R1500 she had sent to herself but only R20 came out, immediately she contacted the call center and she was told she can leave the ATM because she was skeptical to leave incase the machine was jammed, fast forward to today morning she receives an sms saying her dispute was declined because the transaction was successful Ref: She calls the customer care and she is told her transaction was successful she won't be refunded and she shouldn't have left the machine because maybe the machine was jammed. Kindly attend to this at your earliest as she is a student and is relying on these funds to get by
