Ridiculous charges for Factory Fault

I am absolutely appalled with the service Telkom offers or the lack thereof. I took out a mobile contract on the 31st of August 2020 (Samsung device), not even 2 months with this phone, I started experiencing software issues. The Wi-Fi connection, mobile hotspot and the Bluetooth connection stopped working - 2 weeks after that the phone itself wasn't coming on - it was just blank. Last week I took the phone back to Telkom and it was taken in for repairs. Today I receive an SMS stating that I need to pay R4525.25 for the repairs as the device is deemed out of warranty. How am I being charged for a Factory Fault for a phone that's only 2 month old? Their contact center staff is useless as none of them were able to assist or explain as to why I'm being charged so much for a software fault that I didn't even cause. All I'm being told is to go back to the store. Completely useless and I'm so fed up with Telkom.
