Amazon India — order #[protected] additional offer given is not provided

Address:

Ranga Reddy, Andhra Pradesh, 500019

I have purchased one plus 7 on 24th july and as per the offer available on amazon page if i purchase one plus 7 in between 24th and 31st july i was eligible for 12 month protection plan.

It was mentioned that the details would be received within 7 days but until now i didn't receive anything and amazon is telling to contact one plus team for the offer. One plus has denied the offer and amazon is not giving any response on email and in call they are denying the offer.

Please find the attached screenshot of offer displayed on amazon page
