PERELLI TYRES POOR QUALITY L

I have replaced a new Tyres of PERELLI size 245/40 R17 and the 10th April 2023 in Lephalale or Ellisras Hi-Q and I only drove 980 km, my car was already shown signal that is losing air pressures. And get into garage and put correct pressure, do resetting, with a two day again car signal. Now tyre just got damaged. Front tyres were doing the same 225/45 R17 see photos if are needed as evidence.

Now I don't know which to fight with for better service because Hi-Q claims to sell PERELLI TYRE.

your assistance will be highly appreciated
