54 days later and still no answer on repair (within warranty period)

My brother bought a smart TV for my mom and the TV was not updating and we took it in for repairs on 29/08/2025. We were told that it would take 21 days to repair. On Monday being 20 October 2025 I phoned the store again and was advised that they will phone me back as I demanded answers and still no call back as at today being 22 October 2025 and the 21 days has surpassed. Do not support this business if they cannot keep to their contract terms. We want the repaired TV back or a replacement and not a runaround and excuses why 8 weeks later or to be more accurate as at 22/10/2025 54 days later still no answer as to what is happening and when we can expect to collect the TV. How is this treating a costumer fairly or being fair as far as our consumer rights being dismissed by Cash Crusaders
