Device Guru find any scratch to not honor warantee claim

Bought a cell phone through FNB connect. Phone screen went total black from pixel issue within a month just after Xmas 2025. Contact them for warantee claim. Long run around and taking pictures of my phone before they collected it. After another wait told me screen has minute cracks so small it had to be zoomed in 100times to show me. They refused to repair and sent to a quote for R3k to repair avR3.5k Samsung A17. I now paid R750 to get it sent back to me, still waiting since paid 25 Feb.
