Poor service from telkom

I took a contract with Telkom Huawei Nova 9 on the 30th of August 2022 at Mt Frere eastern cape, on the 10th of September 2022 it froze and switched off. And I took it back to them and they told me that they can't give me a new phone because it has passed the 7 days, and then they took it for repairs the reference for repairs TRJ***8 and it came back on the 20th of October then on the 24th of October it did the same thing i took it for repairs for. Now at telkom they refusing to give me a new phone or cancel the contract they want to repair it again for the second time. I don't want that. I want a new phone. My contact number is *** and for telkom it's ***.
