Lenovo — faulty and used laptop sold as new

Address:

122003

I bought a Lenovo laptop (PF1ENMZA) laptop from Croma retail, Gurgaon. From the very first day the laptop had WiFi connecting problem.
I bought the laptop on 7/7/2019 but the warranty is showing to be end on 30/10/2019, though it was supposed to end after one year from the purchase.
I called to the Lenovo Customer Care and they just declined me to send any service person though it was covered with 1 year ON SITE warranty.
After that I took the laptop to the Croma retail, Gurgaon and they suggested me to take it to the service center.
The service center kept my laptop for 3 days and confirmed me that I can take the laptop back and the issue has been resolved.
After I came back the issue revived again just after a couple of hours. I again contacted to the Lenovo customer care
and again they declined to send service executive even though my laptop was in ON SITE warranty and they are well informed that the
laptop is faulty.
