Google play/itunes

Im staying in Lichtenburg and this CNA here the staff does not know anything. I was there today and the manager does not know what the "Google Play" cards are and luaghed at me and thought it was a joke she does not know that there other CNA's sales it. Even my mother had a bad experience there she gave the cashier a R200 note for her sweets and cooldrink and the cashier sweared on her mothers grave that my mother gave her a R50 i was with my mother when she gave the R200 and they refused to look at the cameras. Please look in to it
