Discovered not taking action for substandard workmanship for one of their supplies

I am facing an ongoing issue with a claim that has been unresolved for almost a year now. Despite numerous attempts to communicate—both through multiple emails and phone calls on some days—I have received little to no response.

To make matters worse, I recently discovered additional damage to my vehicle, which appears to be a direct result of substandard workmanship by the panel beater. Based on my experience so far, I am concerned that no action will be taken to address these new issues either.
