poor service

on the 21/05/2021i was so angry by the lazy cashier who wanted to send me back saying the system was not working well for replacing pepmoney card and i should return the next day. and was there previous day ,was told they could not help because they needed R20 for replacement. so i asked that cashier she cant tell me system was not working while was there previous day and system was working smoothly, that's when she called someone from their back office and they helped me with new card with 5minutes only after showing my other side
