Dell India — Non genuine MS office

Address:

GUrgaon

I Have purchased a Dell Laptop on 03/10/2020 with lifetime MS office validity. After a week use, it shows trial is ending and on reaching the dealer he reinstall the MS office and activate the MS office. Now, two ago i am receiving disclaimer while using MS office application that the product is non genuine.

I tried reaching the dealer on phone but his number is not reachable and he is not responding to the mails.
