Vijay Sales — AC issue on 1st day of installation

I have purchased the AC with Model number RAW318HEDO on date 20/June/2021 from Vijay Sales Gurgaon. AC was delivered on 21/June/2021. I opened an installation request with Hitachi CC with ref number [protected]. Installation Engineer visit and Install the AC. During the final inspection I notice AC is giving electric shock. The person who visits for Installation has spent more than 2 hours fixing the issue. But it does not fix the issue.

In between I notice there are lot's of cracks on Back Jali .

I call multiple time to Vijay sales team but no one is ready to take responsibility and either they are ready to listen the issue. My Invoice number is HGD-B-SIS290 to get my contact details.
