Faulty Samsung Galaxy AO3 core

Game from East Rand Mall

My mother purchased a phone back in September 2023 (Samsung Galaxy AO3 core) and oddly enough the phone froze for the whole day after 3 weeks of usage. We had to take it back to Game for "repairs" . After getting the phone back it was fine until it started to freeze and reboot itself after 3 weeks, the phone couldn't be used as it was useless. We had to take it back to Game for "repairs". However game messaged my mother stating that the phone was ready to be collected, but when she went there the staff said they had to take the phone back because it wasn't fixed. Like how can you send something that's not fixed? and it sadly took longer to get it back and bear in mind I was writing NSC final exams and I needed my phone to excess important documents. The manager back then said that he would call my mother, but we still waiting for that call. I eventually got the phone back early December last year, but no surprise it froze and rebooted itself on the 8th of January 2024, just a few weeks after getting it back.Game customer service did call and try to help me as Game, the actual store called me afterwards regarding that issue and I highly appreciate that. The guy said I should bring in the phone and the supplier will check and that it won't even take days and will give us a feedback, but I'm still phoneless as Game said they would take it back for "repairs" I guess. I genuinely don't want that phone as I'm sure it will do the same thing again after few weeks. Im going to university soon and I definitely need a functional phone that's not gonna bother me as I'll be away from home. My mom and I are extremely frustrated going back and forth. I just want a refund or an exchanged phone with the same value. Is that too much to ask?
