Dell India — Issue in recently purchased laptop

I have recently purchased Dell Vostro laptop on 13 Apr-22 through Flipkart portal(from indospirit private limited), after I received it 18 Apr-22. On 29 Apr -22 I faced problem that display shows blur and displayed suddenly not working. But I tried to reach Dell customer support but they are not working on weekend and after 6PM on weekdays . I hope Dell India thinks that their customers beyond those timing ...even they are not reachable through mail ...
And when I checked using my service tag no in dell website it is showing this laptop is purchased on Sept 21 . Does they selling refurbished laptop under new laptop label ...? Doing forgery in sales ...
