Worst app ever i wont recommend it to my worst enemy.

Bought an R100 pauls ice cream voucher after I drove 30km the voucher did not work. This is now the second time that a voucher did not work. My KFC voucher did not work as well. This is unacceptable and I need to be compensated for your incompetence and inconvenience. I am highly irritated and dissatisfied with this app I wont recommend this app to my worst enemy. Clearly a app not worth having on ones cellphone.-- Ruan Schalkwyk
