sold a faulty phone being given the runaround

My sister took a contract with autopage at Cresta Mall for a Huawei P8 for my birthday, I was happy cause my other phone had just died. I noticed it was reading in Manderian (Chinese) because I live in Pretoria I went to the closest Autopage in Centurion Mall. I told the manager when I got the phone and the problem with my music app(s) was in Chinese and the .gif pictures (moving pics) were not working. instead telling me to return it as he was supposed to he tells me to wait for the \expert"who wasn't a technician but a guy who basically memorized the P8 manual otherwise i wouldn't even bothered waiting for him and ask for other options. I couldn't see him because when I get back from work he's already gone. The manager advised me to wait not telling me my one week window period will expire as he is supposed to. Nothing they did worked they all said it was a software issue but after talking to a techion I know its not now they want to take it in for repairs for 3-4wks"
