A 'No cover" warranty at Vodacom

Receved a Galaxy A70 as an upgrade three months ago. The screen went dead and i took it to Vodacom Shelly Beach to be repaired under warranty. Received a message to say that they are not considering the repair under warranty and that the cost would be in excess of R 3000. They said that the screen was cracked despite the fact that, neither the local Vodacom agents who inspected the phone, nor myself, could not find any crack. The rudest woman at their assessment centre, advised "Pay or do whatever you want, but we wont be repairing the phone under warranty."
