Lenovo — Warranty extension of my laptop

Address:

Ferns Icon, Level, 2, Outer Ring Rd, Doddanekundi, Mahadevapura, Bengaluru, Karnataka 560037

I bought laptop(Legion) on 25-Dec-2019 and that time an offer going on (if you bought any laptop you get an extra +2yr extented warranty @Rs.999)whose price without offer is approx Rs.10, 000.Due to this offer I bought Lenovo Legion but to get this offer there is an condition that is you have to extend your warrant within 7day of purchase. But when we go for extension of warranty through online on 5th day of purchase I am totally shocked when I see that my warranty has about to expire within 106 days and showing that warranty start date 20/04/2019 and End on 19/04/2020 so I contact lenovo customer support and he said to drop a mail on [protected]@lenovo.com, So i drop a mail a mail to update the purchase date with my bill. but on next day (6th Day from puchase) when I go for to extend my warranty I found my purchase date are not update so I again contact to customercare executive and they said "you should have to wait 7days to process and this time told me to drop a mail on [protected]@lenovo.com, so i do the same i drop mail, they update my purchase date but on (8th days from purchase).

So due to poor service and lack of support to your customer from lenovo, I didn't have to claim my offer.

I contact many depatment of lenovo to extent my laptop warranty @999 offer they always refer one-another within her department to contact and refuse to provide service because this issue not come under his service like police department.

I also drop mail on various lenevo department on regarding this warranty extension like:-
1.[protected]@lenovo.com
2.[protected]@lenovo.com
3.[protected]@ndslindia.com
4.[protected]@ndcommerce.in
5.[protected]@lenovo.com
6.[protected]@lenovoreg.com
7.[protected]@gmail.com

I also get reply from these department but none of them try to solve my problem some of them refer to contact other department, some of them reply i am not able to solve problem regarding this, and some of them also said that next time when this offer come you contact me i extent your warranty but when i contact at offer time there answer is also same I didn't help in this issue and give me an email to drop a message regarding this.

I am tired of playing email-email, live chat, whatsapp-whatsapp.I also wasted 7 month(it's JULY) in the hope of my problem will we fix.
they didn't even try to contact me and personally to explain why they didn't able to extent my warranty? and where is my fault?And now due lockdown I also not able to contact through call.

I only want to extend my warranty if you not able to extend my warranty then I want full REFUND.
