Bad service

Pick 'n pay of kliptown sux, i once bought a R70 wors and it was rotten, but then they took it wen i returned it. Yesterday i went there to shop at 17:30, they told me that they r closed.but its written that they r closing 18:00.We asked the security to call the manager and he ddint want to.. We were so many and disappointed with their service. Mxm
